Pull KVM fixes from Paolo Bonzini:
- s390: nested virt fixes (new 4.8 feature)
- x86: fixes for 4.8 regressions
- ARM: two small bugfixes
* tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
kvm-arm: Unmap shadow pagetables properly
x86, clock: Fix kvm guest tsc initialization
arm: KVM: Fix idmap overlap detection when the kernel is idmap'ed
KVM: lapic: adjust preemption timer correctly when goes TSC backward
KVM: s390: vsie: fix riccbd
KVM: s390: don't use current->thread.fpu.* when accessing registers
