Merge branch 'percpu-cpumask-x86-for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
* 'percpu-cpumask-x86-for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (682 commits) percpu: fix spurious alignment WARN in legacy SMP percpu allocator percpu: generalize embedding first chunk setup helper percpu: more flexibility for @dyn_size of pcpu_setup_first_chunk() percpu: make x86 addr <-> pcpu ptr conversion macros generic linker script: define __per_cpu_load on all SMP capable archs x86: UV: remove uv_flush_tlb_others() WARN_ON percpu: finer grained locking to break deadlock and allow atomic free percpu: move fully free chunk reclamation into a work percpu: move chunk area map extension out of area allocation percpu: replace pcpu_realloc() with pcpu_mem_alloc() and pcpu_mem_free() x86, percpu: setup reserved percpu area for x86_64 percpu, module: implement reserved allocation and use it for module percpu variables percpu: add an indirection ptr for chunk page map access x86: make embedding percpu allocator return excessive free space percpu: use negative for auto for pcpu_setup_first_chunk() arguments percpu: improve first chunk initial area map handling percpu: cosmetic renames in pcpu_setup_first_chunk() percpu: clean up percpu constants x86: un-__init fill_pud/pmd/pte x86: remove vestigial fix_ioremap prototypes ...
