[PATCH 0/5] x86/percpu semantics and fixes

[Peter Zijlstra]

Hi all,

This is a collection of x86/percpu changes that I had pending and got reminded
of by Linus' comment yesterday about __this_cpu_xchg().

This tidies up the x86/percpu primitives and fixes a bunch of 'fallout'.

Built and boot tested with CONFIG_DEBUG_PREEMPT=y.
