[PULL] drm-intel-gt-next

[Joonas Lahtinen <joonas.lahtinen@linux.intel.com>]

Hi Dave & Sima,

Here goes the singular drm-intel-gt-next PR towards 7.2.

Fix for more robust fence handling after reset on SNB. A couple
UAF/underflow fixes. Selftest improvements and then cleaning up
EXECBUF logic to avoid false positives from AI scanners.

Note that there is a drm-next backmerge to pull in a patch from
mainline tree to revert.

Best Regards, Joonas
