Subject: linux-next: manual merge of the drm-intel tree with the
 drm-intel-fixes tree

Hi all,

Today's linux-next merge of the drm-intel tree got a conflict in:

  drivers/gpu/drm/i915/intel_lrc.c

between commit:

  dfc53c5e73f8 ("drm/i915: Consider HW CSB write pointer before resetting the sw read pointer")

from the drm-intel-fixes tree and commit:

  83843d84fcd3 ("drm/i915: Parametrize LRC registers")

from the drm-intel tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
