efdd06ed18 sgi-xpc: implement opencomplete messaging 
sgi-xpc has a window of failure where an open message can be sent and a
subsequent data message can get lost.  We have added a new message
(opencomplete) which closes that window.

a374c57b07 sgi-xpc: prevent false heartbeat failures 
The heartbeat timeout functionality in sgi-xpc is currently not trained to
the connection time.  If a connection is made and the code is in the last
polling window prior to doing a timeout, the next polling window will see
the heartbeat as unchanged and initiate a no-heartbeat disconnect.

b7f7b07479 sgi-xp: only build for ia64-sn2 when CONFIG_IA64_GENERIC specified 
For the time being build for ia64-sn2 alone when CONFIG_IA64_GENERIC is
specified.

This eliminates a dependency of the XP/XPC drivers on having the GRU
driver insmod'd in order to insmod them, when running on an ia64-sn2
system.

On such a system the GRU driver serves no useful purpose.
