What's 'global irupt mask' and 'global pending'?

You won't get an sync upcall until evtchn_upcall_pending becomes
non-zero. That won't occur until one of the bits in pending_sel
becomes set. Which, in turn, won't occur until an event-channel has
its bit set in the evtchn_pend[] array, which doesn't have its
evtchn_mask[] array bit set.
