Linus,
Please pull the the kvm updates in
git://git.kernel.org/pub/scm/linux/kernel/git/avi/kvm.git for-linus
fixing some x86 emulator and AMD FPU handling regressions.
Amit Shah (2):
KVM: x86 emulator: Use emulator_write_emulated and not emulator_write_std
KVM: SVM: Fix FPU leak while emulating clts
Avi Kivity (1):
KVM: SVM: Unload guest fpu on vcpu_put()
Izik Eidus (2):
KVM: x86 emulator: fix JMP_REL
KVM: x86 emulator: fix the saving of of the eip value
