Merge tag 'topic/kcmp-kconfig-2021-02-22' of git://anongit.freedesktop.org/drm/drm
Pull kcmp kconfig update from Daniel Vetter:
"Make the kcmp syscall available independently of checkpoint/restore.
drm userspaces uses this, systemd uses this, so makes sense to pull it
out from the checkpoint-restore bundle.
Kees reviewed this from security pov and is happy with the final
version"
