Merge branch 'topic/slab/earlyboot-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/penberg/slab-2.6
* 'topic/slab/earlyboot-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/penberg/slab-2.6: slab: setup cpu caches later on when interrupts are enabled slab,slub: don't enable interrupts during early boot slab: fix gfp flag in setup_cpu_cache() x86: make zap_low_mapping could be used early irq: slab alloc for default irq_affinity memcg: fix page_cgroup fatal error in FLATMEM
