| |
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, We need to go with node1 because early_node_map still use 1 for all ranges, and ram from node1 become low ram.
this one fixes BOOTMEM path by loop bdata_list.
-v3: add more comments, and fix bootmem path too. -v4: seperate from one big patch
