The patch titled
NUMA: Add zone_to_nid function
has been removed from the -mm tree. Its filename was
numa-add-zone_to_nid-function-swap_prefetch.patch
This patch was dropped because it was folded into mm-implement-swap-prefetching.patch
------------------------------------------------------
Subject: NUMA: Add zone_to_nid function
From: Christoph Lameter <clameter@xxxxxxx>
There are many places where we need to determine the node of a zone.
Currently we use a difficult to read sequence of pointer dereferencing.
Put that into an inline function and use throughout VM. Maybe we can find
a way to optimize the lookup in the future.
