This little series addresses some problems we've been observing with the
arch timer. First, we were fiddling with a PPI timer interrupt outside
of a preemptible section, which is bad for obvious reasons. Second, we
were clearing the physical active state when we shouldn't. Third, we
can simplify the vgic code by just considering the LR state instead of
the GIC physical state on guest return.
