...ntionally. I'd
have to see some numbers showing making it non-inline is a worth-while
tradeoff.

[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:

- 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
