Świąteczna premiera

19 kwietnia (tuż przed świętami), Linus Torvalds poinformował na kml o wydaniu kolejnej rozwojowej wersji kernela. Tym razem nosi ona numer 2.5.68. Choć 2.5.67 chodzi bardzo stabilnie, nowa wersja wprowadza olbrzymią ilość poprawek. Ich pełną listę znajdziecie w changelogu. Miłego testowania.

  Summary of changes from v2.5.67 to v2.5.68  ============================================      	Aic79XX Driver Update  		- Disable CIO bus stretch of MDFFSTAT so that PCI-X errors can  		  be handled even while the sequencer is reading this register      	Aic79xx Driver Update  	 o On RevA Silicon, modify firmware so that the chip does not violate  	   the P1 setup to datavalid setup time specification.      	Aic79xx Driver Update  	 o Add driver strings for the 39320A adapter.      	Aic79xx Driver Update to version 1.3.2  	 o Fix data corruption issue with Rev A hardware on  	   IBM and Fujitsu U320 Drives.  	 o Fix bug in ahd_pause_and_flushwork() that could prevent recovery  	   actions from being effective.  	 o Correct hang condition caused by attempts by the mid-layer to probe  	   the controller's own ID.      	Update aicasm/Makefile so that link specifications are specified  	after all object files.  This seems to be required in order to  	link correctly in some cases.      	Update Aic7xxx driver to version 6.2.29  	 o Add bus attachment specific hooks for chip-init, suspend and  	   resume.  This is a precursor to better suspend and resume support.  	 o Fix a bug that could cause unnecessary renegotiations after selection  	   timeouts.  	 o Fix a hang that occurred if the mid-layer attempted to probe devices  	   at the controller's own ID.  	 o Add some delays to the termination detection logic for 785X chips.  	   This might resolve some termination problems on very early controllers.      	Update Aic79xx Driver  	 o Fix async negotiation bug when the initial bus reset is  	   disabled if the target device rejects our WDTR of 0.  	 o Fix driver initialization hang if the PCI cacheline size is 0.  	 o Fix typos.  	 o Fix printf arguments to work in both C99 and C89 environments.       	Update aic7xxx driver  	 o Fix async negotiation bug when the initial bus reset is  	   disabled if the target device rejects our WDTR of 0.  	 o Fix typos.  	 o Fix printf formats to work in both C99 and C89 environments.      	Update aic79xx Driver to 1.3.4  	 o Fix stray PCI target abort interrupt on startup due to accessing a  	   register prior to pausing the controller.  	 o Add cfg4icmd implementation.  	 o Fix PCI-X issues on rev A hardware due to improper accesses to  	   scb ram.  	 o Correct a race condition in the error recovery path.      	Update Aic7xxx Driver to 6.2.30  	 o Fix initial DV scan to scan more than just the first target.  	 o Fix compilation on SuSE 2.4.16 kernels.      	Complete Aic7xxx and Aic79xx driver merge with Linux 2.5.X mainline.      	Fix Aic7xxx and Aic79xx Driver builds for 2.4.X.         	ia64: Drop unused NEW_LOCK spinlock code and clean up unneeded test  		in kernel unwinder.      	[PATCH] ia64: CPE & CMC polling for 2.5  	  	Here's another feature I'd like to add to MCA support; the ability  	to detect a flood of CMCs and switch to polling mode for retrieving  	CMC logs.  Once no more CMC logs are found, return to and interrupt  	driven handler.  If the flood threshold is never reached, the CMC  	handler simply behaves as it does today.  	  	   It's useful to get the CMC logs to know that something isn't  	quite right, but if you end up with some bad memory it's too easy for  	them to interfere with useful work.  I've tested this on an HP rx2600,  	with a known bad DIMM.  This DIMM acts like it has a completely dead  	DRAM on it.  With the current CMC handler, once I hit that range of  	memory addresses, the system essentially dies, constantly handling  	CMC errors.  With this patch, the system hits the threshold quickly,  	but remains functional with no performance degredation once in polling  	mode.  This patch applies against linux-2.4.20-ia64-021210 and   	includes:  	  	 - Switching CMCs to polling mode at predeterimined threshold  	 - If polling for CPEs, poll on all processors  	 - Fix timestamp on log output      	[PATCH] ia64: declare test_bit() arg as "const"  	  	While you're fixing bitops.h, making test_bit take a const qualified  	arg will kill some warnings in reiserfs...      	ia64: Remove ia64_spinlock_contention().      	ia64: Rename __put_task_struct() to free_task_struct().  Based on patch by Peter Chubb.      	[PATCH] ia64: clone2/clone argument order fixes  	  	do_fork is declared as:  	struct task_struct *do_fork(unsigned long clone_flags,  	                            unsigned long stack_start,  	                            struct pt_regs *regs,  	                            unsigned long stack_size,  	                            int *parent_tidptr,  	                            int *child_tidptr)  	ie. parent_tidptr is out4 and child_tidptr is out5, but  	the comments in clone2 were suggesting otherwise.  	So, we either need a patch which will codify current order  	of clone arguments (ie. ptid, ctid, tls; attached below - has the advantage  	that clone2 stays with the same ABI as in 2.5.[56]x), or the arguments  	of clone2 and clone should be reordered to match the IA-32 order  	(which is ptid, tls, ctid).      	ia64: Fix settimeofday().  Based on patch by Eric Piel.      	[PATCH] ia64: POSIX timer fixes  	  	Here is a patch to have the POSIX timer interface completly integrated  	in ia64 (2.5.64). The programs in userland can now access the siginfo  	structure. With that patch the test programs of the high resolution  	timers pass without error but one which seems to also be triggered on  	ix86: nanosleeps too short.      	ia64: Fix sys_clone() to take 5 input arguments.      	[PATCH] ia64: unwind.c - allow unw_access_gr(r0)  	  	The patch allows unw_access_gr() to read from r0, to support unwind  	directives such as .save ar.pfs,r0 and .save rp,r0.      	[SERIAL] Remove USR 56K voice modem specific PCI table entry.  	  	Jordan Breeding confirms that our serial PCI detection algorithms  	now correctly determine this device, and doesn't require a specific  	entry.      	ia64: Patch by Andreas Schwab: The read_lock and read_unlock macros  	should not use such innocent variable names like tmp because they  	have a high probability to clash with (part of) the argument.      	[PATCH] ia64: remove stale mmiob function  	  	The consensus on lkml was that devices should do reads from safe  	registers to ensure PIO write ordering, which means we no longer need  	mmiob.  This patch removes the mmiob entries from the machine vector  	headers and io.h and updates the documentation about PIO ordering.      	[AGPGART] Remove unneeded inline.      	[PATCH] ia64: print ISR for FPSWA faults  	  	Here is a simple patch to also print isr during the handling of a  	floating point assist fault.      	[PATCH] ia64: SN makefile update take  	  	David, here's an updated patch that doesn't mess with  	arch/ia64/Makefile in case you hadn't applied the last one yet      	[PATCH] ia64: Use PAL_HALT_LIGHT in cpu_idle  	  	Here's patches for 2.4 & 2.5 to use PAL_HALT_LIGHT in cpu_idle.  	This helps to reduce CPU temp a little on boxes with firmware that  	takes advantage of this lower power state.  I've tried this on a  	rx2600 (2x900MHz McKinley) and an i2000 (fw 117) and it shows some  	benefit.  On McKinley systems, only the very latest PAL from Intel  	actually reduces power consumption in the halt_light state.  For HP  	rx2600/zx6000/zx2000, this means you need to be running firmware 1.82.  	  	  Rohit Seth, at Intel, has ru
n some benchmarks with this kind of  	modification and found the effects of enabling halt_light to fall  	within the noise of mosts tests.  I replaced pal_halt(1) in safe_halt  	with pal_halt_light() since halt_light is required to be implemented,  	but pal_halt(1) is an optional halt state.  I'd be interested to hear  	of any measurements anyone does using this, where it works/fails, and  	if any benchmarks/applications are impacted.      	[PATCH] ia64: improve show_trace_task() portability  	  	Trying to port some patches from i386 to ia64 I've found that  	show_trace_task is the only portable way to show tasks' call  	traces(perhaps because it is called from ./kernel/sched.c:)).  	But its ia64 implementation can't work with running task.  	  	Attached patch fixes this issue.  	  	As I understand show_trace and show_stack are platform  	dependent or have different sense/args.      	ia64: Minor Makefile cleanup.      	First draft at making modules work again (loosely based on Rusty's original and  	thoroughly broken ia64 patch).  Not all relocs are supported yet and the reloc  	code needs to be cleaned up, but simply stuff like loading the palinfo module  	works.  Also, linkage-stubs are optimized with brl for McKinley or better.      	[AGPGART] Kill agp_generic_agp_3_0_enable, fold into agp_generic_agp_enable()      	[AGPGART] namespace cleanup agp_generic_agp_enable -> agp_generic_enable      	[AGPGART] other part of the namespace cleanup patch that got lost.      	[AGPGART] If agp 3.0 setup fails, fall back to agp 2.0 setup      	[AGPGART] bump copyright dates      	[AGPGART] Enable extra VIA GART IDs.  	Now that the generic enable routine can handle agp2 and agp3 setups,  	it should be safe to enable all these.      	[PATCH] ia64: mca rendezvous fix  	  	We are not setting the 'always rendezvous for mca' flag.  kdb needs it  	set to get decent mca debugging on all cpus but I do not want kdb to  	change sal behaviour.  Since we do not recover from mca without a  	debugger, I see no reason why this flag should not be on for all    	kernels.  	  	The rendezvous timeout was set to 100 * HZ, but SAL expects the timeout  	to be in milliseconds, HZ may not be 1 millisecond.  The patch makes  	the timeout an explicit 20 seconds, semi-arbitrary value.      	ia64: Manual merge of Keith Owen's patch to avoid deadlock on  		ia64_sal_mc_rendez().  Also prefix local-variables in  		SAL macros to avoid name collisions.      	[PATCH] ia64: Cross-compile fix  	  	the attached patch (against bk-current) fixes a cross   	compilation problem by using the target specific objdump   	tool instead of the host specific one.      	[AGPGART] New PCI idents for new VIA GARTs      	[ALPHA] Remove parameter list from cond_syscall decl.      	[RAGE 128/CONTROL/PLATNIUM FBDEV] PPC updates.  	  	[RADEON FBDEV] PLL fix for specific type of card.      	[FBCON] Could be called outside of a process context. This fixes that.      	[PATCH] 1/7 starved changes - use a list_head for starved queue's  	  	Use a list_head per scsi_host to store a list of scsi request queues  	that were "starved" (they were not able to send IO because of per host  	limitations).      	[PATCH] 2/7 add missing scsi_queue_next_request calls  	  	Add missing scsi_queue_next_request calls.  	  	Add missing scsi_put_command and scsi_get_command exports.      	[PATCH] 3/7 consolidate single_lun code  	  	Consolidate scsi single_lun code.      	[PATCH] 4/7 cleanup/consolidate code in scsi_request_fn  	  	Cleanup and consolidate scsi_device and scsi_host checks in  	scsi_request_fn.      	[PATCH] 5/7 alloc a request_queue on each scsi_alloc_sdev call  	  	Call scsi_alloc_queue each time we call scsi_alloc_sdev; call  	scsi_free_queue each time we do not find backing LUN.  	  	This code is less optimal, but leads to cleaner code, and the lock  	split-up patch needs this change.      	[PATCH] 6/7 add and use a per-scsi_device queue_lock  	  	Add and use a per scsi_device queue_lock.      	[PATCH] 7/7 fix single_lun code for per-scsi_device queue_lock  	  	Fix single_lun code for per-scsi_device queue_lock      	[FBCON] Now we use workqueues so framebuffer code can always work in a process context.  	  	[GENERIC CURSOR] Safety check in case kmalloc failes      	AICLIB Update  	 o Add aic_parse_brace_option() which handles command line options  	   of the format ":{...{..{}}".  This is used to factor out recurring  	   code in both the aic7xxx and aic79xx drivers.      	Aic79XX Driver Update [Rev 1.3.5]  	 o Clean up driver locking by making the locking semantics between  	   2.4.X and 2.5.X almost identical.  Take advantage of SCSI_HAS_HOST_LOCK  	   in certain RedHat kernels.  	 o Clean up command line parsing.  	 o Fix module unload/reload issues stemming from DV thread teardown  	   and a missing deregistration of our reboot notifier (lost during  	   PCI hot plug integration).  	 o Correct precompensation value used for U320 transfers on  	   rev A4 hardware.  	 o Extract VPD information from the seeprom for potential use  	   in sorting controller probes to match boot order.  	 o Make LED activity more visible on Rev A4 hardware.      	Update Aic7xxx driver [Rev 6.2.31]  	 o Clean up driver locking by making the locking semantics between  	   2.4.X and 2.5.X almost identical.  Take advantage of SCSI_HAS_HOST_LOCK  	   in certain RedHat kernels.  	 o Clean up command line parsing.  	 o Fix module unload/reload issues stemming from DV thread teardown  	   and a missing deregistration of our reboot notifier (lost during  	   PCI hot plug integration).      	[FBDEV] The image color depth of zero hack has been killed.      	ia64: Rewrite the relocator in the kernel module loader.  Fix some bugs and simplify  		the handling of loader-created sections.      	[AGPGART] Make i7x05 compilable again.  	Noticed and partially fixed by Stefan Neuwirth       	ia64: Add ia64-specific LDFLAGS_MODULE and export unwind API to modules.      	ia64: Fix typo in sys_clone().      	ia64: Add module.lds.      	ia64: Minor fixes.      	[I810 FBDEV] Driver updates.  	  	[FBCON] Reversed some of my cursor changes.      	ia64: Fix module loader by setting sh_type of place-holder sesctions to SHT_NOBITS.      	ia64: More module-loader fixing.      	[PATCH] ia64: fix settimeofday() not synchronised with gettimeofday()  	  	Eric Piel wrote:  	> However, now, it still gives negative difference:  	> # ./a.out  	> requested:      1047572128s 2564ns  	> new:            1047572128s 1588ns  	> diff is -0.000976000sec  	>   	> That's better but there is still something...  	> Can anyone reproduce this bug?

This explains the meaning of this line, in the i386  	it's associated with the equivalent line in do_gettimeofday()! On ia64  	everything is done inside of gettimeoffset(). Therefore I'm now  	confident that suppressing this line is a Good Thing ;-) The patch doing  	it wrt the bk tree is attached.  	  	The test case confirms
that it works:  	requested:      1048681051s 194873ns  	new:            1048681051s 194874ns  	diff is  0.000001000sec  	  	That's the same result than on a 2.4.19 .   	This also solved an error on the high resolution timers test suite.      	[PATCH] ia64: fix unwinder bug in unw_access_gr()  	  	I've found this by inspecting the code: pt_regs_off returns an offset into  	struct pt_regs.  Relative to latest bk, 2.5 has the same bug.      	[ARM PATCH] 1363/1: memcpy with preload support and other optimisations  	  	Patch from Nicolas Pitre  	  	This improves on what I did with patch #1362/1 by adding preloads for   	architectures that support it.  On an XScale PXA255 this provides a 20%   	performance gain.  	  	Tested with all combinations of sizes and alignments.      	[ARM PATCH] 1441/2: add preload to the XScale copy_user_page function  	  	Patch from Nicolas Pitre  	  	This should replace patch #1441/1.  	  	This is about 20% faster than the original code, and a few percent faster   	than previous patch.  	  	Tried to add plds to the clear_user_page but it was of no benefit.      	[ARM PATCH] 1442/1: add preload support to page_copy for ARM architectures that support  	 it  	  	Patch from Nicolas Pitre  	  	This requires the definition of PLD added to assembler.h in  	patch #1363/1.      	[ARM PATCH] 1447/1: preload support to uaccess.S  	  	Patch from Nicolas Pitre  	      	[ARM PATCH] 1445/1: [PATCH] removes CONFIG_CPU_{26,32} from arch/arm/kernel  	  	Patch from Ian Molton  	  	see subject.      	[FBDEV] Documentation on the device numbers of /dev/fb being mulitples of 32 is no longer true. Removed that info.  	  	[FBDEV] Logo fixes. Now we can display different color logos on screens of different color depths.  	  	[VGA16 FBDEV] Small compile error. Fixed it now.      	ia64: Two small MCA fixes.      	[PATCH] ia64: update email address  	  	My e-mail address changed and I'd like to update it in arch/ia64/kernel/acpi.c.      	[PATCH] ia64: don't try to synchronize ITCs on ITC_DRIFT platforms  	  	A small patch for 2.4 that stops the kernel from trying to syncrhonize  	ITC clocks between CPUs if we know that the ITC isn't synchronized  	across the backplane.      	[PATCH] ia64: Fix request_module from ia32 process  	  	When an ia32 process triggers request_module the kernel cannot execute  	modprobe because the kernel thread still has the ia32 address limits in  	force.  I think a kernel thread should always have the ia64 address  	limits, similar to what sys32_execve is doing.      	ia64: Patch by Andreas Schwab to fix sys32_ptrace().      	ia64: Change struct ia64_fpreg so it will get 16-byte alignment with all  		ia64 compilers, not just GCC.      	[PATCH] scsi-locking-2.5 rename scsi_check_sdev and  	  	James -  	  	Patch against linux-scsi.bkbits.net/scsi-locking-2.5, per linux-scsi  	discussion.  	  	Rename scsi_check_sdev and scsi_check_shost to scsi_dev_queue_ready  	and scsi_host_queue_ready, and change their return values.  	  	===== drivers/scsi/scsi_lib.c 1.81 vs edited =====      	[PATCH] USB: input class hookup to existing support  	  	Results in this tree /sys/class/input with a combined keyboard/mouse  	USB device:  	  	[root@w-hlinder2 input]# tree /sys/class/input  	/sys/class/input  	|-- devices  	|   |-- 0 -> ../../../devices/pci0/00:0f.2/usb1/1-1/1-1.1/1-1.1:0  	|   |-- 1 -> ../../../devices/pci0/00:0f.2/usb1/1-1/1-1.1/1-1.1:1  	|   `-- 2 -> ../../../devices/pci0/00:0f.2/usb1/1-1/1-1.2/1-1.2:0  	|-- drivers  	|   `-- usb:hid -> ../../../bus/usb/drivers/hid  	`-- mouse      	[PATCH] USB speedtouch: handle failure of usb_set_interface.

[PATCH] USB: ehci-hcd, minor hardware tweaks  	  	This tweaks the hardware in two minor ways, being more forgiving  	of what are either hardware bugs or hard-to-see driver bugs.  	  	  - Some silicon seems to mis-handle dummy qtds on occasion,  	    writing them into the qh and thus stopping progress unless  	    something times it out and cancels it (scsi-eh etc).  	  	    This initializes such qtds slightly differently, so some  	    such cases will make the driver automatically recover, and  	    so all such errors will fail in the same way.  	  	  - In case of dodgy behavior with respect to unlinking, don't  	    modify a field.  Silicon that's (wrongly) reading this will  	    have a chance to read the old value while it's still valid.  	  	Also minor diagnostic tweaks for better uniformity/usability.      	[PATCH] USB: ohci-hcd, pci posting paranoia  	  	Flushes some posted PCI writes in case of trouble.  	Lack of these hasn't been seen to be a problem; the  	update mostly affects run-once init paths.

[PATCH] USB: pegasus link status fix  	  	  fixed up the link status detection      	[PATCH] USB usbnet: dynamic config, cdc-ether, net1080  	  	This patch:  	  	   - Makes "usbnet" pay attention to device descriptors in  	     the most common cases; there's less need to embed device  	     hardware details.  This lets it work with high speed  	     devices, and should help interop with the newer ARM/PXA  	     kernels "usb-eth" (same vid/pid, but different endpoints).  	  	   - Adds some new CDC Ethernet support, which is partly enabled:  	     the Zaurus SL-5500 code uses it, with the current FRAMING_Z  	     flag overriding normal CDC framing on-the-wire.  (Most of  	     the other "minidrivers" use CDC framing, except Net1080  	     and GeneSys.)  	  	   - Merges a patch from Johannes to recover from some net1080  	     framing errors by flushing the fifos ... the chip gets into  	     a wierd mode, this makes the link more robust.  (Thanks!)  	  	   - Gets rid of a family of cpu/logfile saturating loops that  	     could show up in early stages of disconnect processing,  	     while we're getting rx/tx errors continuously since khubd  	     hasn't tried to disconnect() us yet.  (Pathological case,  	     with lots of logging enabled: khubd never gets scheduled!)  	  	   - Uses deeper queues at high speed, so the host controllers  	     can stay busy transferring packets even when IRQs get held  	     off for several milliseconds.  That pipelining gives better  	     throughput too -- 4x more with one device, says TTCP.  	  	With the possible exception of multicast support, this code  	should be a fine replacement to "cdc-ether" ... certainly  	its faster for high speed devices.  Some later patch should  	likely do a switch-over.  (Which would  also resolve a Zaurus  	hotplugging bug:  "cdc-ether" doesn't blacklist it.)      	[PATCH] USB: kerneldoc for usbfs  	  	So far as I know, "usbfs" was never documented ... so  	here's a patch with some text I've had sitting around,  	merging it into the other USB kerneldoc.  	  	It should be accurate, down to the warnings about why  	not to use several of the calls, though cross-review  	with the code would be good too.  A notable omission  	is any details on the async APIs.      	[PATCH] USB: set_configuration() missed some state  	  	I noticed that the usb_set_configuration() code was leaving  	endpoints halted ... likely not a problem just now since that  	routine can't be used safely except during enumeration, but  	better to fix this than not.      	[PATCH] USB: remove redundant checks for NULL when it can never happen.      	kobject: cause /sbin/hotplug to be called when kobjects are added and removed  	  	This only happens if a kobject belongs to a subsystem that has specified  	a set of hotplug operations.

The oops is reliably reproduced by using an EdgePort USB serial  	port in dosemu and then exiting dosemu.  When dosemu closed  	the port the oops would occur.  (Tested in RH 7.3 2.4.18-10.)  	  	The problem was that a USB cmd callback would come in after the  	close with the tty struct freed, and the edge_bulk_out_cmd_callback  	function would do a wakeup on the tty->write_wait queue.  The  	tty struct was gone (I checked that tty->magic was bad) and the  	wakeup would oops.  	  	As you did in other places in io_edgeport.c, I added a check that  	edge_port->open was true before using the edge_port->port->tty  	struct.  	  	I added a similar check in edge_bulk_out_data_callback, though  	I never actually saw the problem here.  	  	I notice that in 2.4.20 a check has been added to be sure that  	edge_port->port->tty is not null--however, this is not enough  	because the tty pointer is not set to null when the port is  	closed.  An alternate solution in 2.4.20 would be to set the  	usb_serial_port->tty pointer to null in usbserial.c serial_close().  	This seems like a good thing to do in general, since the tty  	struct should not be used after a close which frees it.  If  	you would like I investigate this a bit more--it could affect  	other usb serial drivers and reveal some hidden bugs.

Pleas apply after Linus has applied  	the generic part.      	[PATCH] ia64: compat_uptr_t and compat_ptr  	  	Here is the ia64 part of the patch.  It depends on my previous COMPAT  	patches.

[VLAN]: Update to new module semantics, use synchronize_net.      	Add __user/__kernel address space modifiers.

Add the proper sprinkling of __user attributes to the  	user space access functions. This allows the type checker  	to check proper usage.      	Add __user attributes to user pointers in kernel/signal.c. This  	was the first file tested with my type checker with the anal  	pointer attribute checking turned on.      	Make __SI_MASK explicitly unsigned, instead of depending on  	magic C promotion to silently do so for us.      	[IPSEC]: Avoid using SET_MODULE_OWNER.

Annotate x87 user space access functions with proper type attributes.      	[PATCH] i2c: add i2c_clientname()  	  	This patch just adds a #define and a inline function to hide the  	"i2c_client->name" => "i2c_client->dev.name" move introduced by  	the recent i2c updates.  That makes it easier to build i2c drivers  	on both 2.4 and 2.5 kernels.      	[PATCH] i2c: Fix w83781d sensor to use Milli-Volt for in_* in sysfs  	  	I did the w83781d sysfs update as per the old spec, which was not  	milli-volt.  This patch should fix it.

[PATCH] i2c: fix compilation error for various i2c-devices  	  	Changed the i2c_adapter name definition to match the current interface.      	User pointers are not just in another address space, they also  	must never be dereferenced directly. Make that clear in the  	attribute.      	Add user pointer attributes to kernel/sys.c      	[PATCH] fix wait_on_buffer() debug code  	  	The wait_on_buffer() debug code is generating false warnings when called from  	__block_prepare_write().  It is legal to wait on a zero-ref buffer when its  	page is locked.  The page lock keeps try_to_free_buffers() away.  	  	This debug code hasn't found any bugs yet.      	[PATCH] Enforce gcc-2.95 as the minimum compiler requirement  	  	Now that sparc64 is using gcc-3.x we can disallow gcc-2.91, etc.  	  	Documentation/Changes already says 2.95.3, which is working fine for me.  	  	With this change, we no longer require that per-cpu data definitions be  	initialised.  That was a workaround for a bug in older gccs.  So remove the  	build infrastructure which was checking for that.  	  	Also, mention that nfs-utils-1.0.3 is required.  It isn't required yet, but  	will be once we enable larger dev_t: there is an interface for exportfs which  	passes dev_t's into the kernel which breaks with larger dev_t.  That  	interface is old, deprecated and is not used in nfs-utils-1.0.3.      	[PATCH] null-terminate the kmalloc
 tables  	  	From: David Mosberger   	  	The cache_sizes array needs to be NULL terminated, otherwise an oversized  	kmalloc request runs off the end of the table.      	[PATCH] remove nr_reverse_maps VM accounting  	  	Maintaining the `nr_reverse_maps' provides makes a small but  	measurable decrease in page_add_rmap() overhead.  	  	I don't think it's a very useful metric, and it can be sort-of inferred from  	slabinfo.      	[PATCH] speed up rmap searching  	  	several functions in rmap.c are searching the ptes[] array fo find the first  	non-null entry.  	  	Despite the fact tha the whole lot is in L1 cache, it is expensive,  	especially on 128-byte cacheline machines.  	  	We can encode the index of the first non-null pte entry inside the  	pte_chain's `next' field and remove those searches altogether.  	  	This reduces the rmap CPU tax by about 25% on a P4.  For a total runtime  	reduction of around 5% in the bash-script intensive test which I use.      	[PATCH] misc rmap speedups  	  	Even a BUG_ON() makes a measurable difference.  So remove some gratuitous  	ones which will just trigger a null pointer deref anyway.  	  	Also remove some debug code which isn't really being maintained any more.  	  	Also replace (effectively):  	  		test_bit(N, foo);  		set_bit(N, foo);  	  	with  	  		set_bit(N, foo);  		test_bit(N, foo);  	  	In the first case we'll go onto the bus twice: once for the cache miss and  	once to get exclusive write access.  In the second case we only go on the bus  	once.  I think.  Certainly this trick chaved 40% off the cost of  	shrink_list() when I did it there...  	  	This patch is worth 1% or so on the bash script testing.      	[PATCH] Replace the radix-tree rwlock with a spinlock  	  	Spinlocks don't have a buslocked unlock and are faster.

[PATCH] fix unuse_pmd fixme  	  	From: Hugh Dickins   	  	try_to_unuse drop mmlist_lock across unuse_process (with pretty dance  	of atomic_incs and mmputs of various mmlist markers, and a polite new  	cond_resched there), so unuse_process can pte_chain_alloc(GFP_KERNEL)  	and pass that down and down and down and down to unuse_pte: which  	cannot succeed more than once on a given mm (make that explicit by  	returning back up once succeeded).  Preliminary checks moved up from  	unuse_pte to unuse_pmd, and done more efficiently (avoid that extra  	pte_file test added recently), swapoff spends far too long in here.  	Updated locking comments and references to try_to_swap_out.      	[PATCH] JBD pasting warning fix  	  	From: "Hua Zhong"   	  	Fix a token-pasting warning from recent gcc's      	[PATCH] task_vsize() speedup  	  	From: William Lee Irwin III   	  	task_vsize() mysteriously appeared on my profiles.  This should remove it  	from them by using the already in-use elsewhere for rlimit checks  	mm->total_vm for the benefit of O(1) cachelines touched.      	[PATCH] Allow panics and reboots at oops time.  	  	From: Russell Miller   	  	A BUG or an oops will often leave a machine in a useless state.  There is no  	way to remotely recover the machine from that state.  	  	The patch adds a /proc/sys/kernel/panic_on_oops sysctl which, when set, will  	cause the x86 kernel to call panic() at the end of the oops handler.  If the  	user has also set /proc/sys/kernel/panic then a reboot will occur.  	  	The implementation will try to sleep for a while before panicing so the oops  	info has a chance of hitting the logs.  	  	The implementation is designed so that other architectures can easily do this  	in their oops handlers.      	[PATCH] epoll cross-thread deletion fix  	  	From: Davide Libenzi   	  	  	This fixes a bug that might happen having a thread doing epoll_wait() with  	another thread doing epoll_ctl(EPOLL_CTL_DEL) and close(). The fast check  	inside eventpoll_release() is good to not effect performace of code not  	using epoll, but it requires get_file() to be called ( that can be avoided  	by dropping the fast check ). I opted to keep the fast check and to have  	epoll to call get_file() before the event send loop. I tested it on UP and  	2SMP with a bug-exploiting program provided by @pivia.com ( thx to them )  	and it looks fine. I also update the 2.4.20 epoll patch with this fix :      	[PATCH] Missing brelse() in ext2/ext3 extended attribute code  	  	From: Andreas Gruenbacher   	  	Missing brelse() in ext2/ext3 extended attribute code  	  	The ext2 and ext3 EA implementations fail to release a buffer_head if  	the inode that is being accessed is sharing EAs with another inode, and  	an attribute is set to the same value that it has already, like so:  	  	        $ touch f g  		$ setfattr -n user.test -v test f g  		# (Now, both f and g refer to the same EA block.)  		$ setfattr -n user.test -v test f  	  	With the bug, an "invalidate: busy buffer" or "invalidate: dirty  	buffer" message will be logged when the file system is unmounted. This  	patch fixes the problem.  	  	At the implementation level:  	  	The code was assuming that ext3_xattr_cache_find cannot return the same  	block the inode already is associated with, so testing for (old_bh !=  	new_bh) would determine whether the old block is resued or an additional  	bh is held. This is wrong if the EA block is used by multiple inodes (in  	which case it stays in the cache), and the block isn't actually  	modified.  Instead of testing for (old_bh != new_bh), the code now does  	a get_bh() in the branch that keeps the old block, which assures that  	new_bh now is either NULL or a handle that must be released at the end  	of ext3_xattr_set_handle2().      	[PATCH] Make msync(MS_ASYNC) no longer start the I/O  	  	MS_ASYNC will currently wait on previously-submitted I/O, then start new I/O  	and not wait on it.  This can cause undesirable blocking if msync is called  	rapidly against the same memory.  	  	So instead, change msync(MS_ASYNC) to not start any IO at all.  Just flush  	the pte dirty bits into the pageframe and leave it at that.  	  	The IO _will_ happen within a kupdate period.  And the application can use  	fsync() or fadvise(FADV_DONTNEED) if it actually wants to schedule the IO  	immediately.  	  	(This has triggered an ext3 bug - the page's buffers get dirtied so fast  	that kjournald keeps writing the buffers over and over for 10-20 seconds  	before deciding to give up for some reason)      	[PATCH] struct address_space comments  	  	From: "Martin J.

It also gets rid of  	the EISA_bus reference, which is not needed anymore since the driver  	has been ported to the EISA probing API.      	[PATCH] fix file leak in fadvise()  	  	It can miss an fput() if passed the fd of a file which has no ->mapping.

[PATCH] Remove flush_page_to_ram()  	  	From: Hugh Dickins   	  	This patch removes the long deprecated flush_page_to_ram.  We have  	two different schemes for doing this cache flushing stuff, the old  	flush_page_to_ram way and the not so old flush_dcache_page etc. way:  	see DaveM's Documentation/cachetlb.txt.  Keeping flush_page_to_ram  	around is confusing, and makes it harder to get this done right.  	  	All architectures are updated, but the only ones where it amounts  	to more than deleting a line or two are m68k, mips, mips64 and v850.  	  	I followed a prescription from DaveM (though not to the letter), that  	those arches with non-nop flush_page_to_ram need to do what it did  	in their clear_user_page and copy_user_page and flush_dcache_page.  	  	Dave is consterned that, in the v850 nb85e case, this patch leaves its  	flush_dcache_page as was, uses it in clear_user_page and copy_user_page,  	instead of making them all flush icache as well.  That may be wrong:  	I'm just hesitant to add cruft blindly, changing a flush_dcache macro  	to flush icache too; and naively hope that the necessary flush_icache  	calls are already in place.  Miles, please let us know which way is  	right for v850 nb85e - thanks.      	[PATCH] Fix deadlock with ext3+quota  	  	From: Jan Kara   	  	Fixes a deadlock-causing lock-ranking bug between dqio_sem and  	journal_start().

David described it as:  	  	  This is a performance speed up and some minor indendation fixups.  	  	  The problem is that the bootmem code is (a) hugely slow and (b) has  	  execution that grow quadratically with the size of the bootmap bitmap.  	  This causes noticable slowdowns, especially on machines with (relatively)  	  large holes in the physical memory map.  Issue (b) is addressed by  	  maintaining the "last_success" cache, so that we start the next search  	  from the place where we last found some memory (this part of the patch  	  could stand additional reviewing/testing).  Issue (a) is addressed by  	  using find_next_zero_bit() instead of the slow bit-by-bit testing.      	[PATCH] architecture hooks for mem_map initialization  	  	From: Christoph Hellwig   	  	This patch is from the IA64 tree, with minor cleanups from me.  	  	Split out initialization of pgdat->node_mem_map into a separate function  	and allow architectures to override it.  This is needed for HP IA64  	machines that have a virtually mapped memory map to support big  	memory holes without having to use discontigmem.  	  	(memmap_init_zone is non-static to allow the IA64 code to use it -  	 I did that instead of passing it's address into the arch hook as  	 it is done currently in the IA64 tree)      	[PATCH] Fix kmalloc_sizes[] indexing  	  	From: Brian Gerst and David Mosberger  	  	The previous fix to the kmalloc_sizes[] array didn't null-terminate the  	correct array.  	  	Fix that up, and also avoid running ARRAY_SIZE() against an array which is  	really a null-terminated list.      	[PATCH] /proc/interrupts allocates too much memory  	  	From: David Mosberger   	  	interrupts_open() can easily try to kmalloc() more memory than  	supported by kmalloc.  E.g., with 16KB page size and NR_CPUS==64, it  	would try to allocate 147456 bytes.  	  	The workaround below is to allocate 4KB per 8 CPUs.  Not really a  	solution, but the fundamental problem is that /proc/interrupts  	shouldn't use a fixed buffer size in the first place.  I suppose  	another solution would be to use vmalloc() instead.  It all feels like  	bandaids though.      	[PATCH] vmalloc stats in /proc/meminfo  	  	From: Matt Porter   	  	There was a thread a while back on lkml where Dave Hansen proposed this  	simple vmalloc usage reporting patch.  The thread pretty much died out as  	most people seemed focused on what VM loading type bugs it could solve.  I  	had posted that this type of information was really valuable in debugging  	embedded Linux board ports.  A common example is where people do arch  	specific setup that limits there vmalloc space and then they find modules  	won't load.  ;) Having the Vmalloc* info readily available is real useful in  	helping folks to fix their kernel ports.      	[PATCH] /proc/meminfo documentation  	  	From: Dave Hansen   	  	Documents the information in /proc/meminfo      	[PATCH] percpu_counters: approximate but scalable counters  	  	Several places in ext2 and ext3 are using filesystem-wide counters which use  	global locking.  Mainly for the orlov allocator's heuristics.  	  	To solve the contention which this causes we can trade off accuracy against  	speed.  	  	This patch introduces a "percpu_counter" library type in which the counts are  	per-cpu and are periodically spilled into a global counter.  Readers only  	read the global counter.  	  	These objects are *large*.  On a 32 CPU P4, they are 4 kbytes.  On a 4 way  	p3, 128 bytes.      	[PATCH] blockgroup_lock: hashed spinlocks for ext2 and ext3  	  	ext2 and ext3 per-blockgroup metadata needs locking.  An fs-wide lock is  	expensive, and a per-blockgroup lock consumes too much storage (up to 32768  	blockgroups per filesystem).  We need something in-between.  	  	blockgroup_locks are very simple hashed spinlocks which provide this  	compromise.  The size
of the lock is scaled by NR_CPUS to implement an  	additional speed/space tradeoff.  	  	These locks are actually fairly generic.  However I presented it as something  	which is specific to ext2 and ext3 so that people wouldn't go using them all  	over the place.  They consume a lot of storage.      	[PATCH] use spinlocking in the ext2 block allocator  	  	From Alex Tomas and myself  	  	ext2 currently uses lock_super() to protect the filesystem's in-core block  	allocation bitmaps.  	  	On big SMP machines the contention on that semaphore is causing high context  	switch rates, large amounts of idle time and reduced throughput.  	  	The context switch rate can also worsen block allocation: if several tasks  	are trying to allocate blocks inside the same blockgroup for different files,  	madly rotating between those tasks will cause the files' blocks to be  	intermingled.  	  	On SDET and dbench-style worloads (lots of tasks doing lots of allocation)  	this patch (and a similar one for the inode allocator) improve throughout on  	an 8-way by ~15%.  On 16-way NUMAQ the speedup is 150%.  	  	What wedo isto remove the lock altogether and just rely on the atomic  	semantics of test_and_set_bit(): if the allocator sees a block was free it  	runs test_and_set_bit().  If that fails, then we raced and the allocator will  	go and look for another block.  	  	Of course, we don't really use test_and_set_bit() because that  	isn'tendian-dependent.  New atomic endian-independent functions are  	introduced: ext2_set_bit_atomic() and ext2_clear_bit_atomic().  We do not  	need ext2_test_bit_atomic(), since even if ext2_test_bit() returns the wrong  	result, that error will be detected and naturally handled in the subsequent  	ext2_set_bit_atomic().  	  	For little-endian machines the new atomic ops map directly onto the  	test_and_set_bit(), etc.  	  	For big-endian machines we provide the architecture's impementation with the  	address of a spinlock whcih can be taken around the nonatomic ext2_set_bit().  	 The spinlocks are hashed, and the hash is scaled according to the machine  	size.  Architectures are free to implement optimised versions of  	ext2_set_bit_atomic() and ext2_clear_bit_atomic().      	[PATCH] use spinlocking in the ext2 inode allocator  	  	From Alex Tomas and myself  	  	It is identical in concept to the block allocator change.  It uses the same  	hashed spinlock.      	[PATCH] Put all functions in kallsyms  	  	From: Rusty Russell   	  	Introduce _sinittext and _einittext (cf. _stext and _etext), so kallsyms  	includes __init functions.  	  	TODO: Use huffman name compression and 16-bit offsets (see IDE  	oopser patch)      	[PATCH] kNFSd: nfsd/export.c tidyup and add missing exp_put  	  	There was a missing exp_put in export.c so that after a client  	mounts an exported filesystem, the server would never be able to  	unmount, even after trying to unexport.  This is fixed by the last  	chunk of this patch.  	  	Also assorted cleanups to the code found while hunting.      	[PATCH] kNFSd: Return correct result for ACCESS(READ) on eXecute-only file.  	  	Currently, an NFSv3 ACCESS check for READ permission on an  	eXecute-only file will succeed where it should fail.  	  	This is because nfsd_permission allows READ access to eXecute only  	files so that mode 711 executables can be loaded and run, and  	nfsd_access simply uses nfsd_permission.  	  	This patch changes nfsd_permission to only map eXecute permission to  	read permission of MAY_OWNER_OVERRIDE was set.  This is only set  	when trying to read from a file, so ACCESS will no longer be tricked.  	  	This change will only affect callers of nfsd_permission that specify  	MAY_READ and not MAY_OWNER_OVERRIDE, and nfsd_access is the only  	routine that calls nfsd_permission (via fh_verify) that way.      	[PATCH] kNFSd: NFSD binary compatibility breakage  	  	The removal of "struct nfsctl_uidmap" from "nfsctl_fdparm" broke  	binary compatiblity on 64-bit platforms (strictly speaking: on all  	platforms with alignof(void *) > alignof(int)).  The problem is that  	nfsctl_uidmap contained a "char *", which forced the alignment of the  	entire union to be 64 bits.  With the removal of the uidmap, the  	required alignment drops to 32 bits.  Since the first member is only  	32 bits in size, this breaks compatibility with user-space.  Patch  	below fixes the problem.      	[PATCH] kNFSd: First step to adding state management to NFSv4 server  	  	A new file "nfs4state.c", and nfs4_setclientid{,_confirm} are moved there,  	with lots of code.

This patch gets and puts an extra reference to the r1_bio around the  	submission loop, and uses the status in r1_bio to maintain the request status  	if the last refernce is held by make_request.  	  	This is also more correct for write requests, as a write should succeed  	if any write succeeded, not only if the last write succceeded.      	lasi700 add missing dma-mapping.h #include  	  	compile fix for PA-RISC      	sym53c8xx driver v1: PA-RISC needs same PCI command fix as powerpc      	[ARM PATCH] 1453/1: fix clps711x framebuffer "use SRAM?" range  	  	Patch from cam mayor  	  	when setting up the framebuffer on the clps711x platform, the code checks to see if your allocated memory area is less than 38400 bytes.

This was causing a non-deterministic panic  	in the scan code because a destroyed queue was sometimes being  	unplugged and run.      	[PATCH] remove __sk_filter.      	[PATCH] lapic_nmi_watchdog resume fix  	  	I managed to add a bug to the local APIC NMI watchdog's  	resume procedure in the driver model conversion for 2.5.67.  	The problem is that the resume procedure simply calls the  	enable procedure. If the NMI watchdog has been disabled by  	another driver (like oprofile or perfctr), then the NMI  	watchdog will incorrectly be re-enabled.  	  	I discovered this when updating the perfctr driver for 2.5.67  	and seeing unexpected NMIs after a resume from apm --suspend.  	  	We can fix this by unregistering the NMI watchdog from the  	driver model when disabling it (like the code did before the  	driver model changes), or by remembering the previous state  	at suspend and checking it at resume. The patch below uses  	the second, simpler, approach. Tested, please apply.

[PATCH] Fix oprofile on hyperthreaded P4's  	  	From: Philippe Elie   	  	- oprofile is currently only profiling one sibling.  Fix that with  	  appropriate register settings.  	  	- fix an oops which could occur if the userspace driver were to request a  	  non-existent resource.  	  	- in NMI handler counter_config[i].event is accessible from user space so  	  user can change the event during profiling by echo xxx >  	  /dev/oprofile/event  	  	- event mask was wrong, the bit field is 6 bits length not 5, events  	  SSE_INPUT_ASSIST and X87_SIMD_MOVES_UOP was affected by masking high bit of  	  event number.      	[PATCH] flush_work_queue() fixes  	  	The workqueue code currently has a notion of a per-cpu queue being "busy".  	flush_scheduled_work()'s responsibility is to wait for a queue to be not busy.  	  	Problem is, flush_scheduled_work() can easily hang up.  	  	- The workqueue is deemed "busy" when there are pending delayed  	  (timer-based) works.  But if someone repeatedly schedules new delayed work  	  in the callback, the queue will never fall idle, and flush_scheduled_work()  	  will not terminate.  	  	- If someone reschedules work (not delayed work) in the work function, that  	  too will cause the queue to never go idle, and flush_scheduled_work() will  	  not terminate.  	  	So what this patch does is:  	  	- Create a new "cancel_delayed_work()" which will try to kill off any  	  timer-based delayed works.  	  	- Change flush_scheduled_work() so that it is immune to people re-adding  	  work in the work callout handler.  	  	  We can do this by recog
nising that the caller does *not* want to wait  	  until the workqueue is "empty".  The caller merely wants to wait until all  	  works which were pending at the time flush_scheduled_work() was called have  	  completed.  	  	  The patch uses a couple of sequence numbers for that.  	  	So now, if someone wants to reliably remove delayed work they should do:  	  	  		/*  		 * Make sure that my work-callback will no longer schedule new work  		 */  		my_driver_is_shutting_down = 1;  	  		/*  		 * Kill off any pending delayed work  		 */  		cancel_delayed_work(&my_work);  	  		/*  		 * OK, there will be no new works scheduled.  But there may be one  		 * currently queued or in progress.  So wait for that to complete.  		 */  		flush_scheduled_work();  	  	  	The patch also changes the flush_workqueue() sleep to be uninterruptible.  	We cannot legally bale out if a signal is delivered anyway.      	[PATCH] fix tty shutdown race  	  	use-after-free races have been seen due to the workqueue timer in the tty  	structure going off after the tty was freed.  	  	Fix that up by using cancel_scheduled_work() and flush_scheduled_work().      	[PATCH] genrtc: jiffies type fix  	  	use `unsigned long' for a jiffies-holding type.      	[PATCH] export kernel_fpu_begin() to GPL modules  	  	drivers/md/xor.c needs kernel_fpu_begin() for the mmx checksumming functions.  	 So export that to GPL modules.      	[PATCH] Posix timer hang fix  	  	From: george anzinger   	  	The MAJOR problem was a hang in the kernel if a user tried to delete a  	repeating timer that had a signal delivery pending. I was putting the  	task in a loop waiting for that same task to pick up the signal. OUCH!  	  	A minor issue relates to the need by the glibc folks, to specify a  	particular thread to get the signal.  I had this code in all along,  	but somewhere in 2.5 the signal code was made POSIX compliant, i.e.  	deliver to the first thread that doesn't have it masked out.  	  	This now uses the code from the above mentioned clean up.  Most  	signals go to the group delivery signal code, however, those  	specifying THREAD_ID (an extension to the POSIX standard) are sent to  	the specified thread.  That thread MUST be in the same thread group as  	the thread that creates the timer.      	[PATCH] fix MCE startup ordering problems  	  	The MCE code is setting up a timer whose handler uses the workqueue code  	before workqueue is initialised.  If you boot slowly it oopses.  	  	Convert the MCE code to use an initcall.      	[PATCH] Resource management for NFS...  	  	From: Trond Myklebust   	  	The patch fixes some problems with NFS under heavy writeout.  	  	NFS pages can be in a clean but unreclaimable state.  They are unreclaimable  	because the server has not yet acked the write - we may need to "redirty"  	them if the server crashes.  	  	These are referred to as "unstable" pages.  We need to count them alongside  	dirty and writeback pages when making flushing and throttling decisions.  	Otherwise the machine can be flooded with these pages and the VM has  	problems.      	[PATCH] USB: disconnect cleanup, new HCD callback  	  	Here's a streamlined version:  doesn't require the unlink  	cleanup, and expects the *hci-hcd updates later.  Smaller,  	and sanity checked against all three major HCDs.  	  	  - reverts that unlink() patch: disconnect() callbacks  	    can continue to act like they always have.  	  	  - adds new "disable that endpoint" support, necessary  	    for safely changing configurations or altsettings  	    as well as physical disconnect (which is almost the  	    same as setting config to zero, except for ep0).  	  	  - NEW BEHAVIOUR:  usbcore cleans up after drivers that  	    return from disconnect() with urbs still linked, by  	    using the new "disable that endpoint" support.    	  	Because it doesn't have any *hci-hcd updates, the hardware  	synch needed by EHCI and OHCI (not UHCI) still gets done  	through the bus->deallocate(dev) call ... not where we've  	ever needed it, but 2.3-compatible (and finally fixable).  	  	That gets rid of some problematic disconnect scenarios, and  	other fixes can be phased in over time:  the *hci-hcd updates  	to relocate the hardware synch point so it always happens in  	a task context, and disabling endpoints before their configs  	change (invalidating all HC state).        	[PATCH] USB: fix up spin_unlock_irqrestore() issues in previous patch      	[PATCH] USB: add better check to prevent oops in hcd_unlink_urb()      	[PATCH] disconnect cleanup, new HCD callback  	  	Attached, find a patch that "ought to" teach OHCI how to do that  	cleanup, by implementing the new callback.  (And the first half  	is the patch you applied, with that irqsave tweak -- so you should  	already have it.)      	[PATCH] USB: kl5kusb105 fix up errors found by smatch      	[PATCH] USB: kobil_sct fix up errors found by smatch      	[PATCH] USB: DocBook/usb.tmpl patch  	  	remove duplicated word, fix an unclear implication.      	[PATCH] USB scanner.c endpoint detection fix  	  	This patch fixes the endpoint numbers. They were numbered from 1 to n  	but that assumption is not correct in all cases.      	[PATCH] USB: EHCI disconnect cleanup  	  	So here's the EHCI implementation of that new callback,  	morphed/simplified from the old "free_config" one (which  	is now gone).  It looks almost identical to the OHCI  	version, except the dummy TDs work a bit differently.  	  	Again, drivers that clean themselves up in disconnect()  	shouldn't notice this change.  I didn't re-test this;  	I don't have devices with the other kind of driver.  You  	should do so with one of yours (high speed hub and TT).  	  	There are still about half a dozen places in usbcore  	and the HCDs that would benefit from using this new  	callback, FWIW.  I'd call them non-critical bugfixes  	that should wait a bit, while this batch shakes out.      	[PATCH] USB speedtouch: discard packets for non-existant vcc's  	  	I broke part of the udsl_decode_rawcell logic in a previous patch, leading to  	possible hangs on startup/shutdown.  I've attached the 2.4 and 2.5 versions.  	Thanks to Subodh Srivastava and Ted Phelps for their bug reports.

[PATCH] USB: keyspan: fixed up might_sleep() problems on device close.      	[PATCH] {get,set}affinity unification  	  	This one gets rid of sys32_{get,set}affinity in favor of a unified  	compat implementation.      	[PATCH] alpha: execve() fix  	  	The 2.5 kernels may hang on execve(). Most easily this can be reproduced  	by submitting forms in mozilla, apparently because it does execve with  	very long argument strings.  	That's what happens in do_execve, I suppose:  		bprm.mm = mm_alloc();  		...  		init_new_context(current, bprm.mm); here we update current ptbr  						    with new mm->pgd  		...  		copy_strings;  				interrupt -> do_softirq -> switch to ksoftirqd  				...  				switch back to do_execve;  		copy_strings -  immediate page fault in copy_user that we can't  				handle because the new ptbr has been activated  				after context switch and current->mm is not  				valid anymore.  	  	The fix is to not update ptbr for current task in init_new_context(),  	as we do it later in activate_mm() anyway.  	  	With it my (UP) boxes look quite stable so far.  	  	Ivan.      	[PATCH] alpha: move_initrd fix (from Jeff Wiedemeier)  	  	While testing our upcoming kernel update for 7.2 alpha, I've encountered  	a problem with move_initrd. It allocates a page-aligned chunk to move  	the initrd into, but it doesn't allocate the entire last  	page. Subsequent bootmem allo
cations can then be filled from the last  	page used be the initrd.  This then becomes a problem when the initrd  	memory is released.      	[PATCH] alpha: lynx support  	  	Forward port of Jay's 2.4 patch.  	Also I've cleaned up EISA configury - we only need it for  	systems with EISA.  	  	Ivan.      	[ALPHA] Include module.h for EXPORT_SYMBOL.      	Fix typo (and logic bug that the typo hid) in bit value  	testing.   	  	Found by 'sparse', my source parser tool.      	[PATCH] unwinding for vsyscall code  	  	Now that the kernel provides code user programs are executing directly  	(I mean the vsyscall code on x86) it is necessary to add unwind  	information for that code as well.  The unwind information is used not  	only in C++ code.  	  	This patch adds a AT_SYSINFO_EH_FRAME ELF aux-table value that points to  	the unwinding block description for the sysinfo frame, and makes sure  	the AT_* value is passed to applications.  It defines the static data  	for the unwind blocks (two, one for int80 and the other for sysenter),  	and finally adds code to copy the data in place.

Fix whitespace damage.      	[NETFILTER_IPV4]: De-linearization of IP Connection Tracking.  	  	This converts connection tracking and all the connection tracking  	modules to handle non-linear skbs.  Enough interfaces have been  	broken in the process that old helpers won't compile.  	  	Interfaces which used to take a "void *data, int len" or  	"struct iphdr *iph, int len" now take the skb itself (and an offset to  	the data in the case of the first interface), which is not  	linearized in any way (although Alexey says after ip_rcv the IP header  	is always linear, so IPv4 netfilter hooks can always assume a linear  	IP hdr).  	  	Helpers which examine data (amanda, FTP, IRC) now copy it into a buffer  	and examine that.      	[PATCH] module symbol fix  	  	Fix for trivial typo.

I believe the bug was introduced when the fast pathwalk was reverted  	in order to introduce the RCU lockless path walking.      	Annotate sys_nfsservctl() with user pointer annotations      	Fix user pointer annotations in more places, now that 'sparse'  	verifies declarations against definitions and checks argument  	types.

[SERIAL] Move make modem control signals accessible to line discplines  	  	We also parse modem control signals in the tty layer, and fail with  	EINVAL if the driver does not provide the methods.

We need to fix tty.  Meanwhile, let's not gratuitously nuke people's boxes.      	[PATCH] Handle invalid pfns in page_add/remove_rmap  	  	My recent micro-optmisation to these functions broke the pfn_valid()  	checks.  Revert it.      	[PATCH] Fix orlov allocator boundary c
ase  	  	In the interests of SMP scalability the ext2 free blocks and free inodes  	counters are "approximate".  But there is a piece of code in the Orlov  	allocator which fails due to boundary conditions on really small  	filesystems.  	  	Fix that up via a final allocation pass which simply uses first-fit for  	allocation of a directory inode.      	[PATCH] IEEE-1394/Firewire updates  	  	- Add driver registration for dv1394/video1394/raw1394.  	- Fix 3 sleep-while-atomic bugs in ohci1394 and ieee1394.  	- Cleanup some bus-reset handling in ohci1394.  	- Add empty config-rom handling.  	- Check and handle SBP-2 logins active/available for non-exclusive  	  logins.  	- Fix bug in SBP-2 DMA cleanup.

[PATCH] bring devfs_register calls in dvb in shape  	  	Trying to always have a NULL first argument to simplify devfs code  	big time in mid-term.  (Especially in preparation of Adam's smalldevfs).      	[PATCH] make devpts filesystem mandatory even for CONFIG_DEVFS  	  	This patch rips out handling of UNIX98 ptys from devfs.  We already  	have a special small filesystem to handle it (devpts) that's always  	compiled in anyway.  This allows to get rid of all DEVFS_FL* flags and  	some gunk in devfs.      	[PATCH] remove DEVFS_FL_*  	  	Okay, all flags are gone from devfs callers, time to remove the gunk  	handling it.  devfs_register prototype will change later.      	[PATCH] dm devfs fix  	  	Don't pass DEVFS_FL_CURRENT_OWNER to devfs_register, the uid/gid of new  	nodes should always be 0.

[PATCH] devfs: cleanup devfs use in ide  	  	Store the path of it's devfs directory in ide_drive_t.

Makes code cleaner and correctly handles cases like  	   creating a bridge with the same name as an existing ether device etc.  	  	2) Don't do own module ref counting that is inhernently racy.  	   Instead set owner field and cleanup debris on unload.  	  	3) Do last state cleanup in destructor  	  	4) Change of bridge state (dev_open/stop) should use write_lock  	  	5) Make sure timer is not running when cleared.  	  	6) Use "const char *" where possible      	[PATCH] gconfig: bug #540  	  	This replaces checkboxes by radiobuttons whereever necessary (menu  	choices).

[PATCH] struct loop_info64 with __u64  	  	(i) Replace in struct loop_info the dev_t field by __kernel_old_dev_t,  	where this type is defined in , so that problems  	with a differently sized dev_t in userspace are avoided.

[PATCH] correct error message for failed clone ns  	  	If copy_namespace() returns -EPERM, copy_process() will  	return a confusing -ENOMEM. Fix it thus.      	[PATCH] s/to long/too long/      	[PATCH] IEEE-1394/Firewire updates  	  	- Cleaned up hostinfo usage in all drivers and created a central API to  	  handle them all.  	- Fixup some spinlock mis-usage.  	- Remove devfs_handle mis-usage.  	- Cleaned up some heavy handed spinlocking to use mutexes instead.  	- Add function to send PHY config packets and use to to settle  	  IRM/cycle-master/root descrepancies.
