| H A D | atomic.h | diff d0e03218ca3be48c6f7109e4810d58e7b7dd4135 Tue May 25 09:02:07 CDT 2021 Mark Rutland <mark.rutland@arm.com> locking/atomic: atomic: simplify ifdeffery
Now that asm-generic/atomic.h is only used by architectures without any
architecture-specific atomic definitions, we know that there will be no
architecture-specific implementations to override, and can remove the
ifdeffery this has previously required, bringing it into line with
asm-generic/atomic64.h.
At the same time, we can implement atomic_add() and atomic_sub()
directly using ATOMIC_OP(), since we know architectures won't provide
atomic_add_return() or atomic_sub_return().
There should be no functional change as a result of this patch.
