[PATCH] x86_64: Increase NUMA hash function nodemap
Needed for some big Opteron systems to compute a numa hash function They have more than 12 bits significant address. TBD switch this over to dynamic allocation or use better hash Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
