Hi all,

A few too large patches here, mostly as RFC to see if we want to continue with
this before I sink more time into it. I hope they make it out to the lists.

This all started with me wanting to implement atomic_sub_release() for all
archs, but I got side-tracked a bit and it ended up cleaning up bits and
deleting almost 1400 lines of code.

Its been compiled on everything I have a compiler for, however frv and
tile are missing because they're special and I was tired.
