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.
