When the guest executes a WFI instruction the operation is trapped to
KVM, which emulates the instruction in software. There is no correlation
between a guest executing a WFI instruction and actually putting the
hardware into a low-power mode, since a KVM guest is essentially a
process and the WFI instruction can be seen as 'sleep' call from this
process. Therefore, we block the vcpu when the guest excecutes a wfi
instruction and the IRQ or FIQ lines are not raised.

When an interrupt comes in through KVM_IRQ_LINE (see previous patch) we
signal the VCPU thread and unflag the VCPU to no longer wait for
interrupts.

Seems a bit strange tagging this small addition on the end of this series.
Can you merge it in with the rest?
