Subject: sgi-xp/sgi-gru: allow modules to load on non-uv systems
From: Robin Holt <holt@xxxxxxx>
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.
