Merge branch 'linux-4.11' of git://github.com/skeggsb/linux into drm-fixes

GP107 modesetting support (just recognising the chipset, no other changes until 4.12)
a couple of regression fixes, one of them a rather serious double-free issue that appeared in 4.10.
* 'linux-4.11' of git://github.com/skeggsb/linux:
  drm/nouveau: initial support (display-only) for GP107
  drm/nouveau/kms/nv50: fix double dma_fence_put() when destroying plane state
  drm/nouveau/kms/nv50: fix setting of HeadSetRasterVertBlankDmi method
  drm/nouveau/mmu/nv4a: use nv04 mmu rather than the nv44 one
  drm/nouveau/mpeg: mthd returns true on success now
