[Intel-gfx] [PATCH 0/4] PC8 fixes

[Paulo Zanoni]

From: Paulo Zanoni <paulo.r.zanoni at intel.com>

Hi

Patch 1 was sent by Chris a few weeks ago, and patch 2 is my bikeshed to his
original patch. They shouldn't fix any particular bug, and patch 2 will WARN in
case we hit the bug that should not happen.

Patches 3 and 4 fix problems that I discovered while working on the runtime D3.
Since these bugs affect PC8 even without D3, I think they should be merged
before D3. I already have subtests for these problems on the pc8 test, so we
should be fine.

Thanks,
Paulo
