2009-11-18sysctl: Drop & in front of every proc_handler.Eric W. Biederman1-3/+3
For consistency drop & in front of every proc_handler. Explicity taking the address is unnecessary and it prevents optimizations like stubbing the proc_handlers to NULL.

2009-11-12sysctl ia64: Remove dead binary sysctl supportEric W. Biederman1-8/+0
Now that sys_sysctl is a generic wrapper around /proc/sys .ctl_name and .strategy members of sysctl tables are dead code. Remove them. Cc: Tony Luck <tony.luck@intel.com> Cc: Fenghua Yu <fenghua.yu@intel.com> Signed-off-by: Eric W. Biederman <ebiederm@xmission.com>

2009-04-14sgi-xpc: implement opencomplete messagingRobin Holt1-0/+2
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.

2009-04-14sgi-xpc: prevent false heartbeat failuresRobin Holt1-3/+5
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.

2008-10-30sgi-xp: only build for ia64-sn2 when CONFIG_IA64_GENERIC specifiedDean Nelson1-2/+2
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.
