Hi Dave and Daniel,

Fixes for GPU hang, null dereference, suspend-resume, power consumption, and use-after-free.

The commit 6db58901c2aa ("drm/i915/display: return earlier from intel_modeset_init() without display") was not actually a crucial fix, but it allowed a clean pick of the use-after-free one.

Here goes drm-intel-fixes-2020-12-02:

Fixes for GPU hang, null dereference, suspend-resume, power consumption, and use-after-free.

• Program mocs:63 for cache eviction on gen9 (Chris)
• Split the breadcrumb spinlock between global and contexts (Chris)

Please ignore this for now. I was informed that I missed one patch that helps this one here. So I'm going to push a new fixes branch now and will prepare another pull request tomorrow.

• Retain default context state across shrinking (Venkata)
• Limit frequency drop to RPe on parking (Chris)
• Return earlier from intel_modeset_init() without display (Jani)
• Defer initial modeset until after GGTT is initialized (Chris).

Thanks, Rodrigo.
