I guess with that change, we can also dropthe need for other hypercall
introduced in this patch (kvm_pv_kick_cpu_op()). Essentially a vcpu sleeping
because of HLT instruction can be woken up by a IPI issued by vcpu releasing a
lock.
Not if interrupts are disabled.
Hmm yes ..so we need a kick hypercall then.
So then do also you foresee the need for directed yield at some point,
to address LHP? provided we have good improvements to prove.
