xenfb issuing notify_remote_via_irq() too early
...ote_via_irq() in xenfb in that case. Neither would
fix the root issue here, though. (The reason this usually doesn''t cause
any problems in the 2.6.18 tree is that the irq_info array apparently
always ends up being immediately preceded by a 32-bit padding field,
which has the nice effect of EVTCHN_VALID() yielding false for irq -1.)
The call tree which we could (and actually always should) get into that
state is xenfb_probe() -> register_framebuffer() -> fbcon_event_notify()
-> fbcon_fb_registered() -> fbcon_takeover() -> take_over_console()
-> bind_con_driver() -> visual_ini...
