Merge branch 'for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu
Pull percpu updates from Tejun Heo: - Major reorganization of percpu header files which I think makes things a lot more readable and logical than before. - percpu-refcount is updated so that it requires explicit destruction and can be reinitialized if necessary. This was pulled into the block tree to replace the custom percpu refcnting implemented in blk-mq. - In the process, percpu and percpu-refcount got cleaned up a bit * 'for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu: (21 commits) percpu-refcount: implement percpu_ref_reinit() and percpu_ref_is_zero() percpu-refcount: require percpu_ref to be exited explicitly percpu-refcount: use unsigned long for pcpu_count pointer percpu-refcount: add helpers for ->percpu_count accesses percpu-refcount: one bit is enough for REF_STATUS percpu-refcount, aio: use percpu_ref_cancel_init() in ioctx_alloc() workqueue: stronger test in process_one_work() workqueue: clear POOL_DISASSOCIATED in rebind_workers() percpu: Use ALIGN macro instead of hand coding alignment calculation percpu: invoke __verify_pcpu_ptr() from the generic part of accessors and operations percpu: preffity percpu header files percpu: use raw_cpu_*() to define __this_cpu_*() percpu: reorder macros in percpu header files percpu: move {raw|this}_cpu_*() definitions to include/linux/percpu-defs.h percpu: move generic {raw|this}_cpu_*_N() definitions to include/asm-generic/percpu.h percpu: only allow sized arch overrides for {raw|this}_cpu_*() ops percpu: reorganize include/linux/percpu-defs.h percpu: move accessors from include/linux/percpu.h to percpu-defs.h percpu: include/asm-generic/percpu.h should contain only arch-overridable parts percpu: introduce arch_raw_cpu_ptr() ...
