Hi Andrew, I have been asked for a cmpxchg_local implementation by Christoph Lameter so he can use it to accelerate the slub allocator.
On some architectures, where cmpxchg is nothing more that a simple save/restore interrupts surrounding the cmpxchg non atomic ops, I remove the code and make them use the new "generic" version. cmpxchg_local and cmpxchg64_local are made available on all architectures in these patches. They use the best primitive known, either an atomic operation or save/restore interrupts.
