Ravikiran G Thirumalai 10f4dc8b27 [PATCH] x86_64: Fix the node cpumask of a cpu going down 
Currently, x86_64 and ia64 arches do not clear the corresponding bits
in the node's cpumask when a cpu goes down or cpu bring up is cancelled.
This is buggy since there are pieces of common code where the cpumask is
checked in the cpu down code path to decide on things (like in  the slab
down path).  PPC does the right thing, but x86_64 and ia64 don't (This
was the reason Sonny hit upon a slab bug during cpu offline on ppc and
could not reproduce on other arches).  This patch fixes it for x86_64.
I won't attempt ia64 as I cannot test it.

Credit for spotting this should go to Alok.
