1) Correct memory barriers. Routines not returning a value need no memory barriers, however routines returning values do need them. 2) Actually implement non-atomic ext2 bitops. Thanks to Anton Blanchard for pointing out the memory barrier requirements. Signed-off-by: -

Georgi Guninski has some tools that warn about bad user accesses. This one was harmless, but still..

The patch fixes the noexec= boot option on x86_64 to actually work when other options come after it. Credits (if any ;)) should go to Matt Zimmerman and Colin Watson for spotting the problem and providing/testing the fix. Signed-off-by:

The Pentium4 models 0&1 have a longer MSR_EBC_FREQUENCY_ID register as the models 2&3, so the bit shift must be bigger. Signed-off-by:

The hugetlb_page test in do_munmap is too permissive. It checks start vma, but forgets that end vma might be different and huge though start is not: so hits unmap_hugepage_range BUG if misaligned end was given. And it's too restrictive: munmap has always succeeded on unmapped areas within its range, why should it behave differently near a hugepage vma? And the additional checks in is_aligned_hugepage_range are irrelevant here, when the hugepage vma already exists. But the function is still required (on some arches), as the default for prepare_hugepage_range - leave renaming cleanup to another occasion. Signed-off-by:

When looking for identical xattr blocks to share, we were not comparing the name_index fields. This could lead to false sharing when two xattr blocks ended up with identical attribute names and values, and the only default acls. Because acls are cached, the bug was hidden until the next reload of the affected inode. $ mkdir -m 700 a b $ setfacl -m u:bin:rwx a < acl of a goes in the mbcache $ setfacl -dm u:bin:rwx b < acl of b differs only in name_index, so a's acl is reused $ getfacl b < shows the result from the inode cache < empty inode cache (remount, etc.) $ getfacl b < shows an access acl instead of a default acl.

It's time to remove truncate_complete_page's BUG_ON(page_mapped(page)): it was there to give confidence in the new vm_truncate_count mechanism. Earlier releases had no such check, and it wouldn't be at all helpful if it ever bugged up file truncation on a production system - though we don't know of any scenario in which that could happen now.

Just before removing truncate_complete_page's BUG_ON(page_mapped(page)), thought I'd recheck on a few filesystems. The shame! Easily triggered with tmpfs: not because of recent changes, but because shmem_nopage omitted the i_size_read from Andrea's careful truncate_count/i_size_read /cachelookup/truncate_count sequence. For varying reasons, other users of shmem_getpage can't go beyond i_size, so just add it to shmem_nopage. Signed-off-by:

Currently, the kernel won't compile for SMP ppc32 if preempt is enabled. This patch adds suitable read_can_lock and write_can_lock definitions. This patch also adds a real _raw_read_trylock (inline and out-of-line versions), changes the rwlock->lock field to a signed int, which is what it really was all along, and cleans up the out-of-line rwlock code in arch/ppc/lib/locks.c. It removes the debug fields from the rwlock struct because we were never using them, even with CONFIG_DEBUG_SPINLOCK set. I have compile and boot tested this with the four combinations of CONFIG_DEBUG_SPINLOCKS on and off, and CONFIG_PREEMPT on and off. Please put this patch into 2.6.11 so that 2.6.11 will work for ppc32 with CONFIG_SMP and CONFIG_PREEMPT. Signed-off-by:

This patch fixes the issue with HPET on some platforms. According to Vojtech Pavlik: The first write after writing TN_SETVAL to the config register sets the counter value, the second write sets the threshold. When you only do the first write you never set the threshold and interrupts won't be generated properly. Thanks to John Stultz and Andrew Walrond for reporting, root causing the issue and verifying this fix. Signed-off-by:
