We do not chase device info but modparams in this case.

I guess my point from before, (unfortunately I forgot to reply), was how
much of the saving remains if GEM_BUG_ON is compiled out?
Remember the motto of killing off checking globals and only checking
derived state? :) (I'm definitely not in favour of sprinkling more global
checking CAPS over the code.)
Out of the debug build
gen8_cs_irq_handler 170 185 +15
gen8_cs_irq_handler 170 128 -42 (later)
gen8_cs_irq_handler 170 128 -42 (+ USES_GUC_SUBMISSION)

If nothing or almost nothing, I don't see a need to fiddle with this now.
Also please consider later patches which also need conditionals as
execlists is unfortunately gaining new tricks that are harder to pull
off with the current guc submission :|
(Might be time to stop mixing the two backends?)
I might say fine if the commit message contained truth. :)
