Merge branch 'topic/slab/earlyboot' of git://git.kernel.org/pub/scm/linux/kernel/git/penberg/slab-2.6
* 'topic/slab/earlyboot' of git://git.kernel.org/pub/scm/linux/kernel/git/penberg/slab-2.6: vgacon: use slab allocator instead of the bootmem allocator irq: use kcalloc() instead of the bootmem allocator sched: use slab in cpupri_init() sched: use alloc_cpumask_var() instead of alloc_bootmem_cpumask_var() memcg: don't use bootmem allocator in setup code irq/cpumask: make memoryless node zero happy x86: remove some alloc_bootmem_cpumask_var calling vt: use kzalloc() instead of the bootmem allocator sched: use kzalloc() instead of the bootmem allocator init: introduce mm_init() vmalloc: use kzalloc() instead of alloc_bootmem() slab: setup allocators earlier in the boot sequence bootmem: fix slab fallback on numa bootmem: use slab if bootmem is no longer available
