[PATCH] x86_64: Try to allocate node memmap near the end of node
This fixes problems with very large nodes (over 128GB) filling up all of the first 4GB with their mem_map and not leaving enough space for the swiotlb. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
