local_irq_disable() is called before kvmppc_prepare_to_enter().
In patch 4, we call hard_irq_disable() once enter
kvmppc_prepare_to_enter().
And before patch 4, we have the code near the end of
kvmppc_prepare_to_enter() that checks lazy_irq_pending() and aborts
guest entry if there was a race. If I'd known about that bit of code
beforehand, I probably wouldn't have bothered with most of patch 4/4,
but now that it's been done it seems cleaner.
