I've pulled above and it fixes a suspend to RAM issue I've been seeing
in 3.15-rc. Short description of the problem:

On wakeup all seems fine, i.e. hd starts to spin an USB-stuff wakes up.
But all I get from the graphics card is a white screen slowly filling
with random colored pixels. I had to hard reset the system.

GMane seems to be broken currently so I can't post  a link to my
original report.
