Subject: [PATCH 0/2] drm/nouveau: Fix cursor-related display hang

This is a fix for one of the many issues I've been finding on my brand
new desktop. This one in particular is easy to hit if you have a cursor
with a continously updating surface between two displays, what fun!

Reminds me of a another bug from long ago…

Lyude Paul (2):
  drm/nouveau/disp/nv50-: Set lock_core in curs507a_prepare
  drm/nouveau/kms/nv50-: Assert we hold nv50_disp->lock in
    nv50_head_flush_*
