bootmem: reorder code to match new bootmem structure
This only reorders functions so that further patches will be easier to read. No code changed. Signed-off-by: Johannes Weiner <hannes@saeurebad.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
