Merge branch 'slab/next' of git://git.kernel.org/pub/scm/linux/kernel/git/penberg/linux
Pull SLAB changes from Pekka Enberg: "Most of the changes included are from Christoph Lameter's "common slab" patch series that unifies common parts of SLUB, SLAB, and SLOB allocators. The unification is needed for Glauber Costa's "kmem memcg" work that will hopefully appear for v3.7. The rest of the changes are fixes and speedups by various people." * 'slab/next' of git://git.kernel.org/pub/scm/linux/kernel/git/penberg/linux: (32 commits) mm: Fix build warning in kmem_cache_create() slob: Fix early boot kernel crash mm, slub: ensure irqs are enabled for kmemcheck mm, sl[aou]b: Move kmem_cache_create mutex handling to common code mm, sl[aou]b: Use a common mutex definition mm, sl[aou]b: Common definition for boot state of the slab allocators mm, sl[aou]b: Extract common code for kmem_cache_create() slub: remove invalid reference to list iterator variable mm: Fix signal SIGFPE in slabinfo.c. slab: move FULL state transition to an initcall slab: Fix a typo in commit 8c138b "slab: Get rid of obj_size macro" mm, slab: Build fix for recent kmem_cache changes slab: rename gfpflags to allocflags slub: refactoring unfreeze_partials() slub: use __cmpxchg_double_slab() at interrupt disabled place slab/mempolicy: always use local policy from interrupt context slab: Get rid of obj_size macro mm, sl[aou]b: Extract common fields from struct kmem_cache slab: Remove some accessors slab: Use page struct fields instead of casting ...
