[patch 09/23] Add cmpxchg_local, cmpxchg64 and cmpxchg64_local to ia64

[Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca>]

[-- Attachment #1: add-cmpxchg-local-to-ia64.patch --]
[-- Type: text/plain, Size: 1239 bytes --]

Add the primitives cmpxchg_local, cmpxchg64 and cmpxchg64_local to ia64. They
use cmpxchg_acq as underlying macro, just like the already existing ia64
cmpxchg().
