linux/irq.h uses EINVAL but does not #include linux/errno.h. This results in the compiler spitting out errors on some files. Signed-off-by:

throttle_vm_writeout() is designed to wait for the dirty levels to subside. But if the caller holds IO or FS locks, we might be holding up that writeout. So change it to take a single nap to give other devices a chance to clean some memory, then return.

Add some locking to host_ldt_entries to prevent racing when reading LDT information from the host. The locking is somewhat more careful than my previous attempt. Now, only the check of host_ldt_entries is locked. The lock is dropped immediately afterwards, and if the LDT needs initializing, that (and the memory allocations needed) proceed outside the lock. Also fixed some style violations. Signed-off-by:

Fix an oops on the rtc_device_unregister() path by waiting until the last moment before nulling the rtc->ops vector. Fix some potential oopses by having the rtc_class_open()/rtc_class_close() interface increase the RTC's reference count while an RTC handle is available outside the RTC framework. Signed-off-by:

lockdep_init() is marked __init but used in several places outside __init code. This causes following warnings: $ scripts/mod/modpost kernel/lockdep.o WARNING: kernel/built-in.o - Section mismatch: reference to .init.text:lockdep_init from .text.lockdep_init_map after 'lockdep_init_map' (at offset 0x105) WARNING: kernel/built-in.o - Section mismatch: reference to .init.text:lockdep_init from .text.lockdep_reset_lock after 'lockdep_reset_lock' (at offset 0x35) WARNING: kernel/built-in.o - Section mismatch: reference to .init.text:lockdep_init from .text.__lock_acquire after '__lock_acquire' (at offset 0xb2) The warnings are less obviously due to heavy inlining by gcc - this is not altered. Fix the section mismatch warnings by removing the __init marking, which seems obviously wrong. Signed-off-by:

Problem description at: http://bugzilla.kernel.org/show_bug.cgi?id=8048 Commit b18ec803 [PATCH] sched: improve migration accuracy optimized the scheduler time calculations, but broke posix-cpu-timers. The problem is that the p->last_ran value is not updated after a context switch. So a subsequent call to current_sched_time() calculates with a stale p->last_ran value, i.e. accounts the full time, which the task was scheduled away. Signed-off-by:

i.e. one or more drives can be added and the array will re-stripe while on-line. Most of the interesting work was already done for raid5. This just extends it to raid6. mdadm newer than 2.6 is needed for complete safety, however any version of mdadm which support raid5 reshape will do a good enough job in almost all cases (an 'echo repair > /sys/block/mdX/md/sync_action' is recommended after a reshape that was aborted and had to be restarted with an such a version of mdadm).

An error always aborts any resync/recovery/reshape on the understanding that it will immediately be restarted if that still makes sense. However a reshape currently doesn't get restarted. With this patch it does. To avoid restarting when it is not possible to do work, we call into the personality to check that a reshape is ok, and strengthen raid5_check_reshape to fail if there are too many failed devices. We also break some code out into a separate function: remove_and_add_spares as the indent level for that code was getting crazy. Signed-off-by:

md tries to warn the user if they e.g. create a raid1 using two partitions of the same device, as this does not provide true redundancy. However it also warns if a raid0 is created like this, and there is nothing wrong with that. At the place where the warning is currently printer, we don't necessarily know what level the array will be, so move the warning from the point where the device is added to the point where the array is started.

There are two errors that can lead to recovery problems with raid10 when used in 'far' more (not the default). Due to a '>' instead of '>=' the wrong block is located which would result in garbage being written to some random location, quite possible outside the range of the device, causing the newly reconstructed device to fail. The device size calculation had some rounding errors (it didn't round when it should) and so recovery would go a few blocks too far which would again cause a write to a random block address and probably a device error. The code for working with device sizes was fairly confused and spread out, so this has been tided up a bit. Signed-off-by:

When removing set_native_irq I missed the fact that it was called in a couple of places that were compiled even when SMP support is disabled. And since the irq_desc[].affinity field only exists in SMP things broke. Thanks to Simon Arlott <simon@arlott.org> for spotting this. There are a couple of ways to fix this but the simplest one is to just remove the assignments. The affinity field is only used to display a value to the user, and nothing on either i386 or x86_64 reads it or depends on it being any particlua value, so skipping the assignment is safe. The assignment that is being removed is just for the initial affinity value before the user explicitly sets it. The irq_desc array initializes this field to CPU_MASK_ALL so the field is initialized to a reasonable value in the SMP case without being set. Signed-off-by:

Too many changes for comfort since -rc1. Some missed merges, and some just annoyingly big fixes since. This is not how an -rc2 should look. Need to really calm things down!

When the PCI controller OBP node lacks an interrupt-map and interrupt-map-mask property, we need to form the INO by hand. The PCI swizzle logic was not doing that properly. This was a regression added by the of_device code. Signed-off-by: -
