Hi all,
Today's linux-next merge of the tip tree got a conflict in:
arch/arm64/include/asm/atomic.h
between commit:
305d454aaa29 ("arm64: atomics: implement native {relaxed, acquire, release} atomics")
from the arm64 tree and commit:
62e8a3258bda ("atomic, arch: Audit atomic_{read,set}()")
from the tip tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
