[PATCH 09/28] ia64: Provide atomic_{or,xor,and}

[Peter Zijlstra <peterz@infradead.org>]

[-- Attachment #1: peterz-ia64-atomic_logic_ops.patch --]
[-- Type: text/plain, Size: 1770 bytes --]

Implement atomic logic ops -- atomic_{or,xor,and}.

These will replace the atomic_{set,clear}_mask functions that are
available on some archs.
