Cursorily tested it with 4.4.59: the patch applied well like before, kernel
compiled without error-messages, s2disk/s2both/resume all well, no problems so
far.

So it works nicely here but probably needs improvement. I also have not tested
it with newer Intel-CPUs.

The sad thing is that obviously non of the Intel-devs took a look. It shouldn't
take a pro too long (5 minutes?) to see whether the patch is worth improving on
or simply total crap (not here, though). Or provide a better solution at long
last! I had even sent it directly to the guy who had written the a/m committs
and the kernel-maintainer but got no response. So be it, I've done enough in
this matter.

The problems for older Intel CPUs/GPUs started with 4.2 and lasted up to and
including 4.7. That's 6 kernels, including a long-term-kernel that is used by
quite a few distributions, stands at .59 and is still not fixed.
Nothing to be proud of, imo.
