The last use of scratch_space() seems to go away in patch 11 but I
don't see it getting removed anywhere.
There are a bunch of fields now set that were previously only in the
gen8 code e.g:
vs.ThreadDispatchPriority = false;
vs.FloatingPointMode = IEEE754;
vs.IllegalOpcodeExceptionEnable = false;
I take it they are just ignored by previous gens. Maybe something in
the commit message to mention that?
Otherwise this patch is:
