Merge branch 'linus' into locking/core, to resolve conflict
Conflicts: arch/arm/include/asm/percpu.h As Stephen Rothwell noted, there's a conflict between this commit in locking/core: a21ee6055c30 ("lockdep: Change hardirq{s_enabled,_context} to per-cpu variables") and this fresh upstream commit: aa54ea903abb ("ARM: percpu.h: fix build error") a21ee6055c30 is a simpler solution to the dependency problem and doesn't further increase header hell - so this conflict resolution effectively reverts aa54ea903abb and uses the a21ee6055c30 solution.
