Jack Steiner 8741941237 sgi-gru: aSID (context management) bug fixes
This patch fixes bugs related to ASID (context id) management in the GRU
driver.  These changes are all internal to the SGI GRU driver and have no
effect on the base kernel.

Jack Steiner 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.
