[PATCH v3 01/41] lcoking/barriers, arch: Use smp barriers in smp_store_release()
From: Davidlohr Bueso <dave at stgolabs.net>
With commit b92b8b35a2e ("locking/arch: Rename set_mb() to smp_store_mb()")
it was made clear that the context of this call (and thus set_mb)
is strictly for CPU ordering, as opposed to IO. As such all archs
should use the smp variant of mb(), respecting the semantics and
saving a mandatory barrier on UP.
Signe...

[PATCH v3 00/41] arch: barrier cleanup + barriers for virt
Changes since v2:
- extended checkpatch tests for barriers, and added patches
teaching it to warn about incorrect usage of barriers
(__smp_xxx barriers are for use by asm-generic code only),
should help prevent misuse by arch code
to address comments by Russell King
- patched more instances of xen to use virt_ barriers
as suggested by Stefano Stabellini
- implemented a 2 byte xchg on sh

[PATCH v2 00/34] arch: barrier cleanup + barriers for virt
Changes since v1:
- replaced my asm-generic patch with an equivalent patch already in tip
- add wrappers with virt_ prefix for better code annotation,
as suggested by David Miller
- dropped XXX in patch names as this makes vger choke, Cc all relevant
mailing lists on all patches (not personal email, as the list becomes
too long then)
I parked this in vhost tree for now, but the
