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:

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. Signed-off-by: -

Clean up the interface to hrtimers by changing the init code to pass the mode as well as the clock. This allow the init code to select the correct base and eliminates extra timer re-init code in posix-timers. We also simplify the restart interface nanosleep use. Signed-off-by:

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. Signed-off-by:

At the 2.6.12 timeframe ipmi_si_intf.c was patched to provide default register spacings in try_init_acpi() if the register spacing was set to zero, similar to code in other routines. Unfortunately, another patch was simultaneously added that exits early from try_init_acpi() if the register spacings are set to zero, circumventing the new defaults. This patch removes the early exit code and some incorrect comments that aren't present in other common code snippets. Signed-off-by:

Reduce substantially the amount of code using PF_MEMALLOC, as envisaged in the original FIXME. If you're using lvm2, for this patch to work correctly you should update to lvm2 version 2.02.01 or later and device-mapper version 1.02.02 or later. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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.
