Subject: [PATCH v4 0/3] checkpatch: handling of memory barriers

As part of memory barrier cleanup, this patchset
extends checkpatch to make it easier to stop
incorrect memory barrier usage.

This replaces the checkpatch patches in my series
	arch: barrier cleanup + barriers for virt
and will be included in the pull request including
the series.

changes from v3:
	rename smp_barrier_stems to barrier_stems
	as suggested by Julian Calaby.
	add (?: ... ) around a variable in regexp,
	in case we change the value later so that it matters.
changes from v2:
	address comments by Joe Perches:
	use (?: ... ) to avoid unnecessary capture groups
	rename smp_barriers to smp_barrier_stems for clarity
	add barriers before/after atomic
Changes from v1:
	catch optional\s* before () in barriers
	rewrite using qr{} instead of map

Michael S. Tsirkin (3):
  checkpatch.pl: add missing memory barriers
  checkpatch: check for __smp outside barrier.h
  checkpatch: add virt barriers
