Final drm-misc feature pull for 4.15:

UAPI Changes:
- new madvise ioctl for vc4 (Boris)

Core Changes:
- plane commit tracking fixes (Maarten)
- vgaarb improvements for fancy new platforms (aka ppc64 and arm64) by
  Bjorn Helgaas

Driver Changes:
- pile of new panel drivers: Toshiba LT089AC19000, Innolux AT043TN24
- more sun4i work to support A10/A20 Tcon and hdmi outputs
- vc4: fix sleep in irq handler by making it threaded (Eric)
- udl probe/edid read fixes (Robert Tarasov)

And a bunch of misc small cleanups/refactors and doc fixes all over.

KMS cleanups

------------



Some of these date from the very introduction of KMS in 2008 ...



- drm_mode_config.crtc_idr is misnamed, since it contains all KMS object. Should

  be renamed to drm_mode_config.object_idr.



- drm_display_mode doesn't need to be derived from drm_mode_object. That's

  leftovers from older (never merged into upstream) KMS designs where modes

  where set using their ID, including support to add/remove modes.
