[RFC PATCH 0/2] KVM: x86: guest exit microoptimization

[Paolo Bonzini]

This saves about 20 clock cycles per vmexit by avoiding a
local_irq_save/restore pair.  The price is that nested VMX will break
with KVM hosts < 3.16, because the "acknowledge interrupt on exit"
feature becomes mandatory.  What do you think?

Paolo Bonzini (2):
  KVM: x86: always use "acknowledge interrupt on exit"
  KVM: x86: use __kvm_guest_exit
