SGI uses OEM_SAL calls in some of it's online diagnostics. These diagnostics
are run on production systems, both in the factory and at customer sites.
If the SAL call interface is marked _GPL, then these diagnostics cant
be run on standard kernels. 

Since the OEM_SAL call interface restricts SAL calls to the OEM range
of function codes, I dont understand why these calls should be GPL'ed.
