[Intel-gfx] [PATCH 00/18] ppgtt cleanups / scratch merge (v3)

[Mika Kuoppala]

V3 of the ppgtt cleanup series. I dropped the preallocation
of pdps as Michel has patch with updating pdps through ring LRIs
in his 48bit series.

All except 3/18 and 12/18 have Reviewed-bys.

Tomas Elf had concern with 12/18 that the gen9+ hw
cmd parser will NOOP out the commands. Even if it so,
we gain timely hangs and regonizable pattern with older gens.
