[PULL] drm-intel-fixes

[Rodrigo Vivi]

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)
- 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.
