[PATCH] x86_64: Always pass full number of nodes to NUMA hash computation
Previously the numa hash code would be confused by holes in the node space and stop early. This is the first part of the fix for the non boot issue with empty nodes on Opterons. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
