These are grouped into a series largely because of their origin,
not so much because there are heavy dependencies among them.

01: refuse EVTCHNOP_status for Xen-bound event channels
02: avoid race in get_xen_consumer()
03: don't call Xen consumer callback with per-channel lock held
04: evtchn_set_priority() needs to acquire the per-channel lock
05: sched: reject poll requests for unusable ports
06: don't bypass unlinking pIRQ when closing port
07: cut short evtchn_reset()'s loop in the common case
08: ECS_CLOSED => ECS_FREE
09: move FIFO-private struct declarations
10: fifo: use stable fields when recording "last queue" information
11: convert vIRQ lock to an r/w one
12: convert domain event lock to an r/w one
