Subject: [PATCH] sparse: avoid clash with __bitwise and __force from 4.10
 linux/types.h (#5061)

It also used __bitwise and __force. It seems easier to rename
our versions since they are local to this one single header.

Also, undefine them afteerwards, so that we don't pollute the
preprocessor macro namespace.

(cherry picked from commit dc66f33a16596c2886a24da12e56ec096214e124)
