* [PATCH] GFP_ZONETYPES: calculate from GFP_ZONEMASKAndy Whitcroft2006-02-01
| | | | | | | | | | | | GFP_ZONETYPES calculate from GFP_ZONEMASK GFP_ZONETYPES's value is directly related to the value of GFP_ZONEMASK. It takes one of two forms depending whether the top bit of GFP_ZONEMASK is a 'loner'. Supply both forms, enabling the loner.

* [PATCH] Optimize off-node performance of zone reclaimChristoph Lameter2006-02-01
| | | | | | | | | | | | | | | | | | Ensure that the performance of off node pages stays the same as before. Off node pagefault tests showed an 18% drop in performance without this patch. - Increase the timeout to 30 seconds to reduce the overhead. - Move all code possible out of the off node hot path for zone reclaim (Sorry Andrew, the struct initialization had to be sacrificed). The read_page_state() bit us there. - Check first for the timeout before any other checks.

* [PATCH] Mark CONFIG_UFS_FS_WRITE as BROKENAlexey Dobriyan2006-02-01
| | | | | | | | | | | | OpenBSD doesn't see "." correctly in directories created by Linux. Copying files over several KB will buy you infinite loop in __getblk_slow(). Copying files smaller than 1 KB seems to be OK. Sometimes files will be filled with zeros. Sometimes incorrectly copied file will reappear after next file with truncated size.

* [PATCH] powerpc: Add flattened device tree documentationDavid Gibson2006-02-01
| | | | | | | | | | | | | | The flattened device tree is the only supported way of booting ARCH=powerpc kernels on non Open Firmware machines. The documentation for the flattened tree format and contents has been discussed on mailing lists and lately has been living in the dtc git tree. Really, it ought to go in the kernel's Documentation directory for maximum visibility.

* [PATCH] disable lost tick compensation before TSCs are syncedjohn stultz2006-02-01
| | | | | | | | | | | | | | | | Avoid lost tick compensation early in boot before the TSCs are synchronized. Currently timekeeping is enabled before the TSCs are synchronized, thus when the TSCs are synched (reset to zero), it appears that a number of lost ticks have occurred. This can cause premature expiry of timers and in extreme cases can cause the soft lockup detection to fire. This resolves issues reported by Andy Whitcroft as well as bug #5366 reported by Tim Mann.

* [PATCH] sys_sched_getaffinity() & hotplugJack Steiner2006-02-01
| | | | | | | | | | | | | | | | | | | | Change sched_getaffinity() so that it returns a bitmap that indicates the legally schedulable cpus that a task is allowed to run on. Without this patch, if CONFIG_HOTPLUG_CPU is enabled, sched_getaffinity() unconditionally returns (at least on IA64) a mask with NR_CPUS bits set. This conveys no useful infornmation except for a kernel compile option. This fixes a breakage we obseved running recent kernels. We have MPI jobs that use sched_getaffinity() to determine where to place their threads. Placing them on non-existant cpus is problematic :-) Signed-off-by: Jack Steiner <steiner@sgi.com> Acked-by: Ingo Molnar <mingo@elte.hu> Cc: Nathan Lynch <ntl@pobox.com> Cc: Paul Jackson <pj@sgi.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] Introduce __iowrite32_copyBryan O'Sullivan2006-02-01
| | | | | | | | | | | | | | | | | This arch-independent routine copies data to a memory-mapped I/O region, using 32-bit accesses. The naming is double-underscored to make it clear that it does not guarantee write ordering, nor does it perform a memory barrier afterwards; the kernel doc also explicitly states this. This style of access is required by some devices. This change also introduces include/linux/io.h, at Andrew's suggestion. It only has one occupant at the moment, but is a logical destination for oft-replicated contents of include/asm-*/{io,iomap}.h to migrate to.

* [PATCH] hrtimers: fix posix-timer requeue raceakpm@osdl.org2006-02-01
| | | | | | | | | | | | | | | | | | | | | | | From: Steven Rostedtrostedt@goodmis.org <rostedt@goodmis.org> CPU0 expires a posix-timer and runs the callback function. The signal is queued. After releasing the posix-timer lock and before returning to hrtimer_run_queue CPU0 gets interrupted. CPU1 delivers the queued signal and rearms the timer. CPU0 comes back to hrtimer_run_queue and sets the timer state to expired. The next modification of the timer can result in an oops, because the state information is wrong. Keep track of state = RUNNING and check if the state has been in the return path of hrtimer_run_queue. In case the state has been changed, ignore a restart request and do not touch the state variable.

| | | | | | | | | | | | | | | | | | | Clean up the code responsible for the on-disk mirror logs by using the set_le_bit test_le_bit functions of ext2. That makes the BE machines keep the bitmap internally in LE order - it does mean you can't use any other type of operations on the bitmap words but that looks to be OK in this instance. The efficiency tradeoff is very minimal as you would expect for something that ext2 uses. This allows us to remove bits_to_core(), bits_to_disk() and log->disk_bits. Also increment the mirror log disk version transparently to avoid sharing with older kernels that suffered from the 64-bit BE bug.

* [PATCH] powerpc: enable irq's for platform functions.Ben Collins2006-02-01
| | | | | | | | | | | | | Make the platform function interrupt functions actually work. Calls irq_enable() for the first in the list, and irq_disable() for the last. Added *func to struct irq_client so the the user can pass just that to pmf_unregister_irq_client().

* [PATCH] ide-scsi: fix for IDE probe/remove ops changesMikael Pettersson2006-02-01
| | | | | | | | | | | | | | | | | | | | Kernel 2.6.16-rc1 broke the ide-scsi driver: ide-scsi loads but fails to find any devices to bind to. It also triggers a message "Driver 'ide-scsi' needs updating - please use bus_type methods" from the driver core. The IDE core in 2.6.16-rc1 changed the location of an IDE driver's ->probe()/->remove()/->shutdown() methods: they are now in the ide_driver_t struct not in the gen_driver sub-struct. drivers/ide/ was updated for this change but ide-scsi.c wasn't. Hence the breakage. This patch repairs ide-scsi and also eliminates the driver core warning.

* [PATCH] sound/ppc/pmac.c typoBenjamin Herrenschmidt2006-02-01
| | | | | | | | | | | | | | | | | | | In 2.6.16-rc1 there is a small typo introduced by the 'Remove device_node addrs/n_addr' changes which prevents my Powerbook G4 sound from working: Advanced Linux Sound Architecture Driver Version 1.0.11rc2 (Wed Jan 04 08:57:20 2006 UTC). snd: can't request rsrc 0 (Sound Control: 0x80000000:80004fff) ALSA device list: No soundcards found. The patch below fixes it. Of course, the patch fixing the i2c issues ('i2c_smbus_write_i2c_block_data' patch) needs to be applied to in order for the sound to completly work.

* [PATCH] fuse: fix async read for legacy filesystemsMiklos Szeredi2006-02-01
| | | | | | | | | | | | | | | | | | | | | | | While asynchronous reads mean a performance improvement in most cases, if the filesystem assumed that reads are synchronous, then async reads may degrade performance (filesystem may receive reads out of order, which can confuse it's own readahead logic). With sshfs a 1.5 to 4 times slowdown can be measured. There's also a need for userspace filesystems to know whether asynchronous reads are supported by the kernel or not. To achive these, negotiate in the INIT request whether async reads will be used and the maximum readahead value. Update interface version to 7.6 If userspace uses a version earlier than 7.6, then disable async reads, and set maximum readahead value to the maximum read size, as done in previous versions.
