Hi Russell,

Thanks!  I'll validate it with e26a9e00afc4 added to my 3.13
hibernation branch, which includes the OMAP patches, and post the
results.  I can also verify against 3.15-rc1 + hibernation patches,
but there's not much to be done, other than compile test, as the
platform support is not there yet.  I can try rebasing the OMAP stuff
to v3.15-rc1, but I'm not sure what to expect out of that.

In any event, I'll let you know.

Thanks!

Sebastian
