Hi Dave and Sima, This is indeed a hectic week on our drm-xe-fixes. - 10 of the patches here are patches that got recent merged. - 9 are extra patches, mostly workarounds, which were already in drm-xe-next, but not picked up for fixes due the lack of Fixes tag. Lucas had identified them on a backport effort and they look important for the overall stability, hence we are adding this for this round on top of the 10 regular fixes. The conflicts on taking them now were only trivial and solved getting the -next tree versions on a drm-tip rebuild. Everything recorded directly in drm-rerere, with no extra manual conflict handling needed.
