Merge branch 'locking-arch-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull arch atomic cleanups from Ingo Molnar:
"This is a series kept separate from the main locking tree, which
cleans up and improves various details in the atomics type handling:
- Remove the unused atomic_or_long() method
- Consolidate and compress atomic ops implementations between
architectures, to reduce linecount and to make it easier to add new
ops.
- Rewrite generic atomic support to only require cmpxchg() from an
architecture - generate all other methods from that"
