 1.16  19-Dec-2021  riastradh drm: Make some legacy UMS crap build.
 1.15  19-Dec-2021  riastradh Unlock before vfree/kfree, which can sleep, not after.
 1.14  19-Dec-2021  riastradh Fix s/dev->primary->master/dev->master/ missed in merge.
 1.13  18-Dec-2021  riastradh Merge linux-drm-v5-6-rc3
 1.12  14-Feb-2020  maya Reduce diffs by side-loading some header files like Linux.

From riastradh
 1.11  14-Feb-2020  riastradh Reduce diffs by nixing DRM_SUSER macro, deleted upstream long ago.

Instead stub Linux capable(CAP_SYS_ADMIN).
 1.10  14-Feb-2020  riastradh Eliminate -Wpointer-arith patches; use -Wno-pointer-arith instead.
 1.9  27-Aug-2018  riastradh branches: 1.9.6;
Rename drm_core_ioremap -> drm_legacy_ioremap as upstream.
 1.8  27-Aug-2018  riastradh merge linux-drm-v4-4-143
 1.7  29-Apr-2015  riastradh branches: 1.7.16; 1.7.18;
Replace drm_ioremap by drm_core_ioremap, reducing diff a little.
 1.6  16-Jul-2014  riastradh branches: 1.6.2; 1.6.4; 1.6.6;
Make it build and boot on my test machines.

Screen blanks on boot on the Ivy Bridge system with

DRM error in cpt_serr_int_handler: PCH transcoder A FIFO underrun

But after that everything is OK. Appears to be an upstream problem.
To investigate...

I think there's a cache flushing issue somewhere -- there are little
display artefacts on my T60.
 1.5  16-Jul-2014  riastradh fix merge conflicts
 1.4  03-Apr-2014  riastradh branches: 1.4.2; 1.4.4;
Miscellaneous fixes for drm2 on i386.
 1.3  03-Apr-2014  riastradh Fix up removal of _DRM_SHM mappings and the hardware lock.
 1.2  18-Mar-2014  riastradh Merge riastradh-drm2 to HEAD.
 1.1  23-Jul-2013  riastradh branches: 1.1.1;
Initial revision
 1.1.1.4  18-Dec-2021  riastradh Import drm from Linux v5.6-rc3 (commit f8788d86ab28f61f7b46eb6be375f8a726783636)

 1.1.1.1.2.12  24-Jul-2013  riastradh drm_bufs.c doesn't need <asm/mtrr.h> after all (drmP.h gets it).

 1.1.1.1.2.10  24-Jul-2013  riastradh For _DRM_CONSISTENT maps, hang the dmah on the drm_local_map.

The way the Linux code does it is a bookkeeping kludge that falls
down when we want to maintain more than just the PCI bus address, as
drm mmap will want in order to avoid vtophys.

 1.1.1.1.2.5  24-Jul-2013  riastradh agp_info.ai_aperture_size, not agp_info.aper_size << 20, in drm_bufs.c.
