The old drivers for user-space mode setting have been removed in Linux v6.3. No one has complained or requested their return. It is time to remove these drivers' infrastructure from the DRM core.

The recent Linux v6.6 has been designated as long-term release, [1] so any remaining users have a few more years to get a new graphics card. The legacy devices continue to be supported via simpledrm. Merging proper drivers with kernel mode setting is also an option. Patches 1 to 7 fix a few trivial issues that have been forgotten during the removal of the drivers. Patches 8 and 9 remove the leagcy ioctl interfaces. One op is different from the others, so it gets its own patch. Patches 10 to 12 remove the legacy source code from DRM. With that gone patch 13, the AGP code can be simplified as well. There used to be a device file for user-space mode setting, /dev/agpgart, that is now obsolete. Patch 14 removes the option from Kconfig.
