Page migration: Do not accept invalid nodes in the target nodeset
has been removed from the -mm tree. Its filename was
page-migration-do-not-accept-invalid-nodes-in-the-target-nodeset.patch
This patch was dropped because it is obsolete
------------------------------------------------------
Subject: Page migration: Do not accept invalid nodes in the target nodeset
From: Christoph Lameter <clameter@xxxxxxx>
Page migration currently does not check if the target of the move contains
nodes that that are invalid and may try to allocate from invalid nodes if
these are specified leading to oopses.
Return -EINVAL if a node is specified that is not known to have memory.
