Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull KVM fixes from Radim Krčmář:
"ARM:
- Fix handling of the 32bit cycle counter
- Fix cycle counter filtering
x86:
- Fix a race leading to double unregistering of user notifiers
- Amend oversight in kvm_arch_set_irq that turned Hyper-V code dead
- Use SRCU around kvm_lapic_set_vapic_addr
- Avoid recursive flushing of asynchronous page faults
- Do not rely on deferred update in KVM_GET_CLOCK, which fixes #GP
- Let userspace know that KVM_GET_CLOCK is useful with master clock;
4.9 changed the return value to better match the guest clock, but
didn't provide means to let guests take advantage of it"
