Make __ffs result type unsigned long to match generic asm
implementation. This fixes the following build warning:
mm/nobootmem.c: In function '__free_pages_memory':
include/linux/kernel.h:742:17: warning: comparison of distinct pointer
types lacks a cast
(void) (&_min1 == &_min2); \
^
mm/nobootmem.c:100:11: note: in expansion of macro 'min'
order = min(MAX_ORDER - 1UL, __ffs(start));
