[PATCH] x86_64: Support memory hotadd without sparsemem
Memory hotadd doesn't need SPARSEMEM, but can be handled by just preallocating mem_maps. This only needs some untangling of ifdefs to enable the necessary code even without SPARSEMEM. Originally from Keith Mannthey, hacked by AK. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
