Whoever did the PCI revision patch slipped up on the it821x, and I didn't spot this at the time either. They moved the check for the errata from the 0x10 revision to 0x11. Put it back This one is important for 2.6.23 final as in some cases bad things will occur if 0x10 revision boards don't get the fixups. Signed-off-by:

The NUMA layer only supports NUMA policies for the highest zone. When ZONE_MOVABLE is configured with kernelcore=, the the highest zone becomes ZONE_MOVABLE. The result is that policies are only applied to allocations like anonymous pages and page cache allocated from ZONE_MOVABLE when the zone is used. This patch applies policies to the two highest zones when the highest zone is ZONE_MOVABLE. As ZONE_MOVABLE consists of pages from the highest "real" zone, it's always functionally equivalent. The patch has been tested on a variety of machines both NUMA and non-NUMA covering x86, x86_64 and ppc64. No abnormal results were seen in kernbench, tbench, dbench or hackbench. It passes regression tests from the numactl package with and without kernelcore= once numactl tests are patched to wait for vmstat counters to update. akpm: this is the nasty hack to fix NUMA mempolicies in the presence of ZONE_MOVABLE and kernelcore= in 2.6.23. Christoph says "For .24 either merge the mobility or get the other solution that Mel is working on. That solution would only use a single zonelist per node and filter on the fly. That may help performance and also help to make memory policies work better." Signed-off-by:

Xen i386 xen-head.S fix sections mixup xen-head.S does not come back to the data section, leaving the text section as current section. It causes problems with a slightly enhanced DEBUG_RODATA that supports CONFIG_HOTPLUG and bringing a CPU up after the text has been marked read-only: reference to early_gdt_descr causes a page fault. Updates: - It should be using pushsection/popsection. - Actually, the push/popsections around the ELFNOTEs are redundant; ELFNOTE() does its own push/popsection to put things into the appropriate .note* section anyway.

de_thread: if (atomic_read(&oldsighand->count) <= 1) BUG_ON(atomic_read(&sig->count) != 1); This is not safe without the rmb() in between. The results of two correctly ordered __exit_signal()->atomic_dec_and_test()'s could be seen out of order on our CPU. The same is true for the "thread_group_empty()" case, __unhash_process()'s changes could be seen before atomic_dec_and_test(&sig->count). On some platforms (including i386) atomic_read() doesn't provide even the compiler barrier, in that case these checks are simply racy. Remove these BUG_ON()'s. Alternatively, we can do something like BUG_ON( ({ smp_rmb(); atomic_read(&sig->count) != 1; }) ); Signed-off-by:Oleg Nesterov <oleg@tv-sign.ru> Acked-by:

This one-liner patch fixes a bug in drivers/auxdisplay/cfag12864b.c At cfag12864b_init(), the driver tries to kalloc some memory in the variable cfag12864b_cache. Then, as usual, it checks if the call failed. However, it checks cfag12864b_buffer instead. This patch changes the "cfag12864b_buffer" to "cfag12864b_cache" so the correct variable is checked.

Due to inconsistent locking in the VFS between calls to lookup and revalidate deadlock can occur in the automounter. The inconsistency is that the directory inode mutex is held for both lookup and revalidate calls when called via lookup_hash whereas it is held only for lookup during a path walk. Consequently, if the mutex is held during a call to revalidate autofs4 can't release the mutex to callback the daemon as it can't know whether it owns the mutex. This situation happens when a process tries to create a directory within an automount and a second process also tries to create the same directory between the lookup and the mkdir. Since the first process has dropped the mutex for the daemon callback, the second process takes it during revalidate leading to deadlock between the autofs daemon and the second process when the daemon tries to create the mount point directory. After spending quite a bit of time trying to resolve this on more than one occassion, using rather complex and ulgy approaches, it turns out that just delaying the hashing of the dentry until the create operation works fine.

The previous patch which limited the number of sectors in a single request to a COWed device was correct in concept, but the limit was implemented in the wrong place. By putting it in ubd_add, it covered the cases where the COWing was specified on the command line. However, when the command line only has the COW file specified, the fact that it's a COW file isn't known until it's opened, so the limit is missed in these cases. This patch moves the sector limit from ubd_add to ubd_open_dev. Signed-off-by:

Commit 17571284 was slightly bad. If an array has a write-intent bitmap, and you remove a drive, then readd it, only the changed parts should be resynced. However after the above commit, this only works if the array has not been shut down and restarted. This is because it sets 'fullsync' at little more often than it should. This patch is more careful.

It seems a simple mistake was made when converting follow_hugetlb_page() over to the VM_FAULT flags bitmasks (in "mm: fault feedback #2", commit 83c54070). By using the wrong bitmask, hugetlb_fault() failures are not being recognized. This results in an infinite loop whenever follow_hugetlb_page is involved in a failed fault. Signed-off-by:

Skip calling cache_free_alien() when the platform is not numa capable. This will avoid cache misses that happen while accessing slabp (which is per page memory reference) to get nodeid. Instead use a global variable to skip the call, which is mostly likely to be present in the cache. This gives a 0.8% performance boost with the database oltp workload on a quad-core SMP platform and by any means the number is not small :) Signed-off-by:

With this patch any thread can dequeue its own private signals via signalfd, even if it was created by another sub-thread. To do so, we pass "current" to dequeue_signal() if the caller is from the same thread group. This also fixes the scheduling of posix timers broken by the previous patch. If the caller doesn't belong to this thread group, we can't handle __SI_TIMER case properly anyway. Perhaps we should forbid the cross-process signalfd usage and convert ctx->tsk to ctx->sighand.

dequeue_signal: if (__SI_TIMER) { spin_unlock(&tsk->sighand->siglock); do_schedule_next_timer(info); spin_lock(&tsk->sighand->siglock); } Unless tsk == curent, this is absolutely unsafe: nothing prevents tsk from exiting. If signalfd was passed to another process, do_schedule_next_timer() is just wrong. Add yet another "tsk == current" check into dequeue_signal(). This patch fixes an oopsable bug, but breaks the scheduling of posix timers if the shared __SI_TIMER signal was fetched via signalfd attached to another sub-thread. Mostly fixed by the next patch.

sys_timer_create() sets ->it_process and unlocks ->siglock, then checks tmr->it_sigev_notify to define if get_task_struct() is needed. We already passed ->it_id to the caller, another thread can delete this timer and free its memory in between. As a minimal fix, move this code under ->siglock, sys_timer_delete() takes it too before calling release_posix_timer(). A proper serialization would be to take ->it_lock, we add a partly initialized timer on posix_timers_id, not good. Signed-off-by:
