Disable (via ugly #if 0's) the 3 sysfs files that I think by now we all agree are very much wrong. These files shouldn't become part of the ABI by the 2.6.16 release, so I rather have this minimal patch merged to disable them for now, the real fix can then come during the 2.6.17 devel window.

One can do "chattr +j" on a file to change its journalling mode. Fix writeback mode with "nobh" handling for it. Even though, we mount ext3 filesystem in writeback mode with "nobh" option, some one can do "chattr +j" on a single file to force it to do journalled mode. In order to do journaling, ext3_block_truncate_page() need to fallback to default case of creating buffers and adding them to transaction etc. Signed-off-by: NBadari Pulavarty <pbadari@us.ibm.com> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

This patch fixes illegal __GFP_FS allocation inside ext3 transaction in ext3_symlink(). Such allocation may re-enter ext3 code from try_to_free_pages. But JBD/ext3 code keeps a pointer to current journal handle in task_struct and, hence, is not reentrable. This bug led to "Assertion failure in journal_dirty_metadata()" messages. http://bugzilla.openvz.org/show_bug.cgi?id=115Signed-off-by: NAndrey Savochkin <saw@saw.sw.com.sg> Signed-off-by: NKirill Korotaev <dev@openvz.org> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

The cache reaper currently tries to free all alien caches and all remote per cpu pages in each pass of cache_reap. For a machines with large number of nodes (such as Altix) this may lead to sporadic delays of around ~10ms. Interrupts are disabled while reclaiming creating unacceptable delays. This patch changes that behavior by adding a per cpu reap_node variable. Instead of attempting to free all caches, we free only one alien cache and the per cpu pages from one remote node. That reduces the time spend in cache_reap. However, doing so will lengthen the time it takes to completely drain all remote per cpu pagesets and all alien caches. The time needed will grow with the number of nodes in the system. All caches are drained when they overflow their respective capacity. So the drawback here is only that a bit of memory may be wasted for awhile longer. Details: 1. Rename drain_remote_pages to drain_node_pages to allow the specification of the node to drain of pcp pages. 2. Add additional functions init_reap_node, next_reap_node for NUMA that manage a per cpu reap_node counter. 3. Add a reap_alien function that reaps only from the current reap_node. For us this seems to be a critical issue. Holdoffs of an average of ~7ms cause some HPC benchmarks to slow down significantly. F.e. NAS parallel slows down dramatically. NAS parallel has a 12-16 seconds runtime w/o rotor compared to 5.8 secs with the rotor patches. It gets down to 5.05 secs with the additional interrupt holdoff reductions.

Currently the code tries up to spin_retry times to grab a lock using the cs instruction. The cs instruction has exclusive access to a memory region and therefore invalidates the appropiate cache line of all other cpus. If there is contention on a lock this leads to cache line trashing. This can be avoided if we first check wether a cs instruction is likely to succeed before the instruction gets actually executed.

ATI chipsets tend to generate double timer interrupts for the local APIC timer when both the 8254 and the IO-APIC timer pins are enabled. This is because they route it to both and the result is anded together and the CPU ends up processing it twice. This patch changes check_timer to disable the 8254 routing for interrupt 0. I think it would be safe on all chipsets actually (i tested it on a couple and it worked everywhere) and Windows seems to do it in a similar way, but to be conservative this patch only enables this mode on ATI (and adds options to enable/disable too) Ported over from a similar x86-64 change. I reused the ACPI earlyquirk infrastructure for the ATI bridge check, but tweaked it a bit to work even without ACPI. Inspired by a patch from Chuck Ebbert, but redone.

A recent change to compat. dev_ifconf() in fs/compat_ioctl.c causes ifconf data to be truncated 1 entry too early when copying it to userspace. The correct amount of data (length) is returned, but the final entry is empty (zero, not filled in). The for-loop 'i' check should use <= to allow the final struct ifreq32 to be copied. I also used the ifconf-corruption program in kernel bugzilla #4746 to make sure that this change does not re-introduce the corruption.

A pte may be zapped by the swapper, exiting process, unmapping or page migration while the accessed or dirty bit handers are about to run. In that case the accessed bit or dirty is set on an zeroed pte which leads the VM to conclude that this is a swap pte. This may lead to - Messages from the vm like swap_free: Bad swap file entry 4000000000000000 - Processes being aborted swap_dup: Bad swap file entry 4000000000000000 VM: killing process .... Page migration is particular suitable for the creation of this race since it needs to remove and restore page table entries. The fix here is to check for the present bit and simply not update the pte if the page is not present anymore. If the page is not present then the fault handler should run next which will take care of the problem by bringing the page back and then mark the page dirty or move it onto the active list.
