[PATCH] x86_64: Allocate cpu local data for all possible CPUs
CPU hotplug fills up the possible map to NR_CPUs, but it did that after setting up per CPU data. This lead to CPU data not getting allocated for all possible CPUs, which lead to various side effects. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
