Some holiday stable kernel updates

Given that the same bug is also present in Linus's tree, we are doing well with being "bug compatible" here :)

Anyway, seems to be a compiler issue, see the long thread. It's easy to work around at the moment (change compiler versions or change kernel build options), so there are known solutions at the moment.

It's a shame these things happen, but I guess it highlights the fact that CPUs that aren't commonly found in “developer machines” are basically the wild west as far as support goes. I had a similar problem with a recent glibc crashing on Atom chips - that was a bit harder to recover from, but I learned why Busybox is installed by default that day…

Note that 4.14.9 has caused a spate of issues, including inability to boot machines with CONFIG_MCORE2=y. Gentoo has masked it. See https://lkml.org/lkml/2017/12/28/64 and https://bugs.gentoo.org/642268. I was lucky and saw the message on LKML before rebooting. Very sloppy for a stable release.
