Paul Mackerras 8464c8842d KVM: PPC: Book3S HV: Fix H_PROD to actually wake the target vcpu
The H_PROD hypercall is supposed to wake up an idle vcpu.  We have
an implementation, but because Linux doesn't use it except when
doing cpu hotplug, it was never tested properly.  AIX does use it,
and reported it broken.  It turns out we were waking the wrong
vcpu (the one doing H_PROD, not the target of the prod) and we
weren't handling the case where the target needs an IPI to wake
it.  Fix it by using the existing kvmppc_fast_vcpu_kick_hv()
function, which is intended for this kind of thing, and by using
the target vcpu not the current vcpu.

We were also not looking at the prodded flag when checking whether a
ceded vcpu should wake up, so this adds checks for the prodded flag
alongside the checks for pending exceptions.
