Okay, had a long talk with mpee and benh on IRC, where a few things came
out of it:
1) This is absolutely an upstream kernel bug.
2) This code probably doesn't work on anything newer than a G5 *anyway*, even
if they fix that one line.
Given those two points, the conclusion we came to is that we should
disable CONFIG_HIBERNATION for ppc64el, and they'll backburner an item
to some day see if they can make hibernation work on modern POWER CPUs,
but no one sees that as critical.
I did a testbuild on ppc64el with CONFIG_HIBERNATION=n, and that worked
fine, so that's what we should do for now.

Title:
Disable CONFIG_HIBERNATION on ppc64el
Status in linux package in Ubuntu:
Confirmed
Bug description:
We have uploaded our first 4.0 based Wily kernel to the archive but
are unfortunately seeing the following build failure which we believe
is related to our wily toolchain:

ppc64el.linux_4.0.0-1.1_BUILDING.txt.gz

We do not believe this is due to a kernel change as the code in
question has not changed in years. Additionally, we had 4.0 based
test builds successfully passing in our PPA (ppa:canonical-kernel-
team/ppa). The last successful test build in our PPA was from May 21
(the logs are still there if needed). We were also unable to
reproduce by cross-compiling.
As added information, our wily kernel git repo can be seen at:

Let us know if any additional information is required to debug this.
