a24e5e1caf sgi-gru: change GRU CCH commands from inline functions to outofline functions
Change the GRU instructions that manage contexts from inline functions to
out-of-line functions.  This simplifies adding statistics & error checking
to these functions.

fe5bb6b00c sgi-gru: misc GRU cleanup
Misc trivial GRU drivers fixes:
	- fix long lines
	- eliminate extra whitespace
	- eliminate compiler warning
	- better validation of invalidate user parameters
	- bug fix for GRU TLB flush (not the cpu TLB flush)

These changes are all internal to the SGI GRU driver and have no effect
on the base kernel.
