| |
Currently, free_all_bootmem_core() assumes that the bdata for a given node will begin where the node's memory map begins. This isn't necessarily true on machines that use a virtual memory map (e.g. ia64 discontig machines), so we fix page to point to the first actual page of RAM on the node, which _does_ contain the bdata struct.
Thanks, Jesse
