sgi-xp/sgi-gru: allow modules to load on non-uv systems

2009-04-21T20:41:50Z

For an upcoming distro release, we need to have the xp kernel module loadable even when not on UV equipment. The xpc module will not load. This will allow one set of modules dependent upon xp to work on either UV or non-UV equipment.

sgi-xpc: implement opencomplete messaging

2009-04-13T22:04:33Z

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. Signed-off-by: Robin Holt Signed-off-by: Dean Nelson Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

sgi-xpc: prevent false heartbeat failures

2009-04-13T22:04:33Z

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.

sgi-xp: fix writing past the end of kzalloc()'d space

2009-02-05T20:56:49Z

A missing type cast results in writing way beyond the end of a kzalloc()'d memory segment resulting in slab corruption. But it seems like the better solution is to define ->recv_msg_slots as a 'void *' rather than a 'struct xpc_notify_mq_msg_uv *' and add the type cast.

sgi-xp: link XPNET's net_device_ops to its net_device structure

2009-02-03T23:16:48Z

A recent patch by Stephen Hemminger to convert XPNET to use net_device_ops and internal net_device_stats failed to link the net_device_ops structure to the net_device structure.
