Tony, please check this and fix it. If it's a false warning please let
us know.

I tried to re-pro by:
git checkout 5ad4d8957b69f3ebf95ac02212c388bda75aeb30
# save the attached .config to linux build tree
make ARCH=i386
But cannot see it. And I checked the code, looks fine to me.
It seems to be a false warning.

Hi, what's your compiler? we can reproduce by gcc-4.9 and follow above steps.
From https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53119 , the warning should be only on old compilers.
If made below change, the warning will disappear.

Oh, my gcc version is 5.5.0 20171010.
OK, then I know it should be fixed for old gcc versions.
Thanks!
