[PATCH] mm/slob.c: for_each_possible_cpu(), not NR_CPUS
Convert for-loops that explicitly reference "NR_CPUS" into the potentially more efficient for_each_possible_cpu() construct. Signed-off-by: John Hawkes <hawkes@sgi.com> Cc: Matt Mackall <mpm@selenic.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
