Merge branch 'drm-nouveau-fixes-3.9' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-next 

Lots of thermal fixes and fix a lockdep warning we've been seeing.

* 'drm-nouveau-fixes-3.9' of git://anongit.freedesktop.org/git/nouveau/linux-2.6:
  drm/nv50/kms: prevent lockdep false-positive in page flipping path
  drm/nouveau/core: fix return value of nouveau_object_del()
  drm/nouveau/hwmon: do not expose a buggy temperature if it is unavailable
  drm/nouveau/therm: display the availability of the internal sensor
  drm/nouveau/therm: disable temperature management if the sensor isn't readable
  drm/nouveau/therm: disable auto fan management if temperature is not available
  drm/nv40/therm: reserve negative temperatures for errors
  drm/nv40/therm: disable temperature reading if the bios misses some parameters
  drm/nouveau/therm-ic: the temperature is off by sensor_constant, warn the user
  drm/nouveau/therm: remove some confusion introduced by therm_mode
  drm/nouveau/therm: do not make assumptions on temperature
  drm/nv40/therm: increase the sensor's settling delay to 20ms
  drm/nv40/therm: improve selection between the old and the new style
