slub: Fix signedness warnings
The bit-ops routines require its arg to be a pointer to unsigned long. This leads sparse to complain about different signedness as follows: mm/slub.c:2425:49: warning: incorrect type in argument 2 (different signedness) mm/slub.c:2425:49: expected unsigned long volatile *addr mm/slub.c:2425:49: got long *map Acked-by: Christoph Lameter <cl@linux.com> Acked-by: David Rientjes <rientjes@google.com> Signed-off-by: Namhyung Kim <namhyung@gmail.com> Signed-off-by: Pekka Enberg <penberg@kernel.org>
