Merge branch 'linux-3.17' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-fixes

A couple of thinkos from the -next merge, some random fixes from a
coverity scan, fix for (at least) GK106 accidentally using
non-existent vram on some board configurations, and better behaviour
of the instmem allocations if vmalloc space runs out.

* 'linux-3.17' of git://anongit.freedesktop.org/git/nouveau/linux-2.6:
  drm/nouveau/platform: fix compilation error
  drm/nouveau/gk20a: add LTC device
  drm/nouveau: warn if we fail to re-pin fb on resume
  drm/nouveau/nvif: fix dac load detect method definition
  drm/gf100-/gr: fix -ENOSPC detection when allocating zbc table entries
  drm/nouveau/nvif: return null pointers on failure, in addition to ret != 0
  drm/nouveau/ltc: fix tag base address getting truncated if above 4GiB
  drm/nvc0-/fb/ram: fix use of non-existant ram if partitions aren't uniform
  drm/nouveau/bar: behave better if ioremap failed
  drm/nouveau/kms: nouveau_fbcon_accel_fini can be static
  drm/nouveau: kill unused variable warning if !__OS_HAS_AGP
  drm/nouveau/nvif: fix a number of notify thinkos
