bootmem, x86: Fix 32bit numa system without RAM on node 0
When 32bit numa is used, free_all_bootmem() will still only go over with node id 0. If node 0 doesn't have RAM installed, the lowest populated node becomes low RAM. This one fixes BOOTMEM path by iterating over the bdata_list. -v3: add more comments, and fix bootmem path too. -v4: seperate from one big patch Signed-off-by: Yinghai Lu <yinghai@kernel.org> LKML-Reference: <4BB416D7.6090203@kernel.org> Signed-off-by: H.
