Hi Dave, Sima,

The only fix in this week's cycle is re-enabling the CCS modifiers on DG2
which got accidentaly disabled some time ago.

Hi Dave & Sima,

Here's still a drm-intel-fixes PR towards 7.0. Took a few more hours
as Linus seems to prefer the EXECBUF fix via -fixes rather than -next.

One display fix for SU area WARN in PSR code, for GT refcount underflow
fix in hangcheck and removal condition on execbuf BO processing which
gives a false alert of a bug in mainline.

Regards, Joonas

Also, if you haven't been following all the discussion, the execbuf
cleanup here removes the need for the fix that Linus applied himself to
v7.0-rc7. This just removes the condition check that is always true,
avoiding false alarm of a bug in current mainline.
