  kvm: x86: merge kvm_arch_set_irq and kvm_arch_set_irq_inatomic (2016-11-19 19:04:19 +0100)

----------------------------------------------------------------
KVM fixes for v4.9-rc6

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
