powerpc: make __ffs return unsigned long
I'm seeing a build warning in mm/nobootmem.c after removing
bootmem:
mm/nobootmem.c: In function '__free_pages_memory':
include/linux/kernel.h:713:17: warning: comparison of distinct pointer types lacks a cast [enabled by default]
(void) (&_min1 == &_min2); \
^
mm/nobootmem.c:90:11: note: in expansion of macro 'min'
order = min(MAX_ORDER - 1UL, __ffs(start));
^
The rest of the worlds seems to define __ffs as returning unsigned long,
so lets do that.
