[PULL] drm-intel-fixes

[Rodrigo Vivi]

Hi Dave and Daniel,

A special thanks to our CI and to Chris here.

https://intel-gfx-ci.01.org/tree/drm-intel-fixes/index.html

For finding and providing the quick fix for 5.4 on time to avoid
the bad corruption with fbdev mmap.

Plus other kernel oops and corruption fixes.

There was a conflict here with drm-next but it was easy to
solve and it is recorded on drm-rerere so that might be transparent
now.

More details below.

Here goes drm-intel-fixes-2019-11-21:

- Fix kernel oops on dumb_create ioctl on no crtc situation
- Fix bad ugly colored flash on VLV/CHV related to gamma LUT update
- Fix unity of the frequencies reported on PMU
- Fix kernel oops on set_page_dirty using better locks around it
- Protect the request pointer with RCU to prevent it being freed while we might need still
- Make pool objects read-only
- Restore physical addresses for fb_mmap to avoid corrupted page table

Thanks,
Rodrigo.
