Before releasing something like this, where none of us is sure if
it really saves cpu cost, I'd prefer to run some measurement with

vcpu wake ups with the number of interrupts to be processed by
the gib alert mechanism in a slightly over committed host while
driving with Matthews test load.
But I think patch 1 and 2 can go immediately as they measurably or
testable fix things. Correct?
I think so as well. And if patch 3 is going to be dropped, I would
really like to keep the unconditional clear in kvm_arch_vcpu_runnable(),
as my analysis in the discussion points out: I think it can save us
form trouble this patch is trying to address.
Yes, lets keep patch 1 and 2 as us and let us look deeper into this patch.
I will apply and queue 1 and 2 soon.
