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.
