Good job.

IMO, ARM atomic.h should have cmpxchg and the other standard atomic routines
so applications don't roll their own and they become stale.

This will help application writers if we move the atomic commands from the
ARMv4/ARMv5 ARM_RAS_START/ARM_RAS_END atomic method to ARMv6/ARMv7
ldrex/strex/clrex commands.
