[PATCH v2 43/43] KVM: VMX: Don't do full kick when handling posted interrupt wakeup

[Sean Christopherson]

When waking vCPUs in the posted interrupt wakeup handling, do exactly
that and no more.  There is no need to kick the vCPU as the wakeup
handler just need to get the vCPU task running, and if it's in the guest
then it's definitely running.
