Merge branch 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86
Pull x86 platform drivers from Matthew Garrett:
"Small set of updates, mainly trivial bugfixes and some small updates
to deal with newer hardware.
There's also a new driver that allows qemu guests to notify the
hypervisor that they've just paniced, which seems useful."
