[PATCH] EDAC: atomic scrub operations
EDAC requires a way to scrub memory if an ECC error is found and the chipset does not do the work automatically. That means rewriting memory locations atomically with respect to all CPUs _and_ bus masters. That means we can't use atomic_add(foo, 0) as it gets optimised for non-SMP This adds a function to include/asm-foo/atomic.h for the platforms currently supported which implements a scrub of a mapped block. It also adjusts a few other files include order where atomic.h is included before types.h as this now causes an error as atomic_scrub uses u32.
