The patch titled
mm/slob.c: for_each_possible_cpu(), not NR_CPUS
has been removed from the -mm tree. Its filename is
mm-slobc-for_each_possible_cpu-not-nr_cpus.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.
From: John Hawkes <hawkes@xxxxxxx>
Convert for-loops that explicitly reference "NR_CPUS" into the potentially
more efficient for_each_possible_cpu() construct.
