Pull up revision 1.3 (requested by bouyer in ticket #193):
Add polling support to the domain controller. Use this in xencons instead
of relying on the fact that the domain controller is still getting interrupts
when xenconscn_getc()/xenconscn_putc() is called.
Now that polling is fixed, move IPL_CTRL down between IPL_SOFTSERIAL and
IPL_TTY, fixing port-xen/29999 by YAMAMOTO Takashi.
Now that IPL_CTRL is low enouth, remove the softintr stuff from the
domain controller, and call wakeup() directly.
Thanks to YAMAMOTO Takashi and Christian Limpach for feedback and suggestions.
