Reminds me of

commit 70962fbe5c75e785d250c04db4d01c18b7316c13

    drm/i915: Remove disable_lite_restore_wa

    This w/a (WaEnableForceRestoreInCtxtDescForVCS) was only used for
    preproduction hw, which is no longer in use.  Remove the workaround to
    simplify the code.

but that is only mentioned for VCS, whereas we see the PREEMPT | COMPLETED on,
at least, bcs.
