This series continues the arch atomic rework started with the smp_mb__
interface cleanup.

In this series we (mostly) reduce the atomic implementations by eliminating
repetition through use of CPP macros.

A future series will use these macros to implement more atomic ops. With these
macros we can end up with more atomic ops while the total LoC still shrinks.

Furthermore, rewrite the asm-generic/atomic implementations to require less and
provide more.

This series is compile tested on a number of archs, but only boot tested on
x86_64.

What's the status on this series? I'm currently fleshing out 
an extension to the atomic API that allows more flexible 
acquire/release semantics and it doesn't make sense for me to 
copy-paste a bunch of code when I could build it on top of 
this instead.

Its in tip/locking/arch and I suppose its headed for the next 
merge window.

Correct, there are no known regressions with the tip:locking/arch 
tree so I plan to send those changes to Linus in the merge 
window.

Thanks,

	Ingo
