Sean Christopherson 4ab5d1b709 KVM: x86: Ensure deadline timer has truly expired before posting its IRQ ... commit beda430177f56656e7980dcce93456ffaa35676b upstream. When posting a deadline timer interrupt, open code the checks guarding __kvm_wait_lapic_expire() in order to skip the lapic_timer_int_injected() check in kvm_wait_lapic_expire(). The injection check will always fail since the interrupt has not yet be injected. Moving the call after injection would also be wrong as that wouldn't actually delay delivery of the IRQ if it is indeed sent via posted interrupt.
