[PATCH 0/23] make atomic_read() and atomic_set() behavior consistent across all architectures

By popular demand, I've redone the patchset to include volatile casts in atomic_set as well. I've also converted the macros to inline functions, to help catch type mismatches at compile time.

This will do weird things on ia64 without Andreas Schwab's fix:

Notably absent is a patch for powerpc. I expect Segher Boessenkool's assembly implementation should suffice there:

Thanks to all who commented on previous incarnations.
