No, we can't apply this as is--see the recent revert of a similar
change, below.
kstrtoint does not have the same behavior as simple_strtol, so don't
blindly replace one by the other. At a bare minimum the changelog
should have a note about the differences to help maintainers determine
if the change will cause problems.

commit 621eb19ce1ec216e03ad354cb0c4061736b2a436

svcrpc: Revert "sunrpc/cache.h: replace simple_strtoul"
Commit bbf43dc888833ac0539e437dbaeb28bfd4fbab9f "sunrpc/cache.h: replace
simple_strtoul" introduced new range-checking which could cause get_int
to fail on unsigned integers too large to be represented as an int.
We could parse them as unsigned instead--but it turns out svcgssd is
actually passing down "-1" in some cases. Which is perhaps stupid, but
there's nothing we can do about it now.
So just revert back to the previous "sloppy" behavior that accepts
either representation.
