Subject: [PATCH] - UV fix compile error on IA64 & eliminate compiler warning


The GRU driver is used on both IA64 & x86.
The 2 architectures have different ways of detecting the
platform type, ie. whether the platform is a UV system.
Although it is possible to reconcile the 2 methods,
only one place currently makes the test.

Also eliminate a warning message in uv.h.
