Merge branch 'core-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull NUMA balancing memory corruption fixes from Ingo Molnar: "So these fixes are definitely not something I'd like to sit on, but as I said to Mel at the KS the timing is quite tight, with Linus planning v3.12-final within a week. Fedora-19 is affected: comet:~> grep NUMA_BALANCING /boot/config-3.11.3-201.fc19.x86_64 CONFIG_ARCH_SUPPORTS_NUMA_BALANCING=y CONFIG_NUMA_BALANCING_DEFAULT_ENABLED=y CONFIG_NUMA_BALANCING=y AFAICS Ubuntu will be affected as well, once it updates the kernel: hubble:~> grep NUMA_BALANCING /boot/config-3.8.0-32-generic CONFIG_ARCH_SUPPORTS_NUMA_BALANCING=y CONFIG_NUMA_BALANCING_DEFAULT_ENABLED=y CONFIG_NUMA_BALANCING=y These 6 commits are a minimalized set of cherry-picks needed to fix the memory corruption bugs. All commits are fixes, except "mm: numa: Sanitize task_numa_fault() callsites" which is a cleanup that made two followup fixes simpler. I've done targeted testing with just this SHA1 to try to make sure there are no cherry-picking artifacts. The original non-cherry-picked set of fixes were exposed to linux-next for a couple of weeks" * 'core-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: mm: Account for a THP NUMA hinting update as one PTE update mm: Close races between THP migration and PMD numa clearing mm: numa: Sanitize task_numa_fault() callsites mm: Prevent parallel splits during THP migration mm: Wait for THP migrations to complete during NUMA hinting faults mm: numa: Do not account for a hinting fault if we raced
