atomic: Collapse all atomic_{set,clear}_mask definitions
Browse files Browse the repository at this point in the history
Move the now generic definitions of atomic_{set,clear}_mask() into
linux/atomic.h to avoid endless and pointless repetition.

Also, provide an atomic_andnot() wrapper for those few archs that can
implement that.
