bootmem: reorder interface functions and add a missing one
Impact: cleanup and addition of missing interface wrapper The interface functions in bootmem.h was ordered in not so orderly manner. Reorder them such that * functions allocating the same area group together - ie. alloc_bootmem group and alloc_bootmem_low group. * functions w/o node parameter come before the ones w/ node parameter. * nopanic variants are immediately below their panicky counterparts. While at it, add alloc_bootmem_pages_node_nopanic() which was missing. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Johannes Weiner <hannes@saeurebad.de>
