Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull kvm fixes from Paolo Bonzini:
"Bugfixes, mostly for ARM and AMD, and more documentation.
Slightly bigger than usual because I couldn't send out what was
pending for rc4, but there is nothing worrisome going on. I have more
fixes pending for guest debugging support (gdbstub) but I will send
them next week"
