Merge branch 'linux-4.7' of git://github.com/skeggsb/linux into drm-fixes

Fixes for two issues reported by KASAN, a display engine hang due to
incorrect BIOS table parsing, and incorrect LTC interrupt handling on
Maxwell which could lead to a never-ending interrupt storm.

* 'linux-4.7' of git://github.com/skeggsb/linux:
  drm/nouveau/disp/sor/gm107: training pattern registers are like gm200
  drm/nouveau/disp/sor/gf119: both links use the same training register
  drm/nouveau/core: swap the order of imem/fb
  drm/nouveau/fbcon: fix out-of-bounds memory accesses
  drm/nouveau/gr/gf100-: update sm error decoding from gk20a nvgpu headers
  drm/nouveau/ltc/gm107-: fix typo in the address of NV_PLTCG_LTC0_LTS0_INTR
  drm/nouveau/bios/disp: fix handling of "match any protocol" entries
