The patch titled
PowerMac: force only suspend-to-disk to be valid
has been removed from the -mm tree. Its filename is
powermac-force-only-suspend-to-disk-to-be-valid.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.

Subject: PowerMac: force only suspend-to-disk to be valid
From: Johannes Berg <johannes@xxxxxxxxxxxxxxxx>
For a very long time, echoing 'standby' or 'mem' into /sys/power/state has
killed the machine on powerpc. This patch fixes that.
This patch adds the .valid callback to pm_ops on PowerMac so that only the
suspend to disk state can be entered. Note that just returning 0 would
suffice since the upper layers don't pass PM_SUSPEND_DISK down, but we
handle it there regardless just in case that changes.
