[PULL] drm-xe-next

[Thomas Hellstrom <thomas.hellstrom@linux.intel.com>]

Hi Dave, Simona

This week's drm-xe-next PR (Rodrigo is out this week).

Two big series, the SRIOV scheduler groups, and
multi-device SVM. The latter may conflict somewhat with
fixes, but conflict resolutions are in drm-rerere and
should be resolved to the -next code anyway.

The multi-device SVM also touches UAPI.

Thanks,
Thomas
