Do you have any reason why having the code at vcpu_put/vcpu_load is
better than the proposal to have the code at kvm_vcpu_block?
I think your proposal is good, I just want to better understand your idea

Should SN be already clear (and NV set to POSTED_INTR_VECTOR)?
I think the SN bit should be clear here, Adding it here is just to make sure
SN is clear when vCPU is blocked, so it
