4946980099 drm/nve0: allow specification of channel engine type in abi16 call
Previously, if either vram/gart handles were specified as ~0, the ioctl
call would fail.  In order to hack engine selection into the ioctl for
kepler, we now define (fb_ctxdma_handle == ~0) to mean "engine mask is
in tt_ctxdma_handle".

This approach also allows new userspace to detect lack of support for
non-PGRAPH channels on older kernels.

eed6187d9f drm/nouveau/pm: do not stop reclocking if failing to set the fan speed
With the introduction of fan management modes, fan may not be drivable.
We should allow reclocking nonetheless.

This return was stupid to begin with since it may have left the card
in an intermediate state (clocks corresponding to a perflvl and voltage
corresponding to another one). The reclocking code will need to be
rewritten in a near-future in order to provide a better error handling.

  The rest is general grab bag of fixes.

  So why part 1? well I have the exynos pull req which came in a bit
  late but was waiting for me to do something they shouldn't have and it
  looks fairly safe, and David Howells has some more header cleanups
  he'd like me to pull, that seem like a good idea, but I'd like to get
  this merge out of the way so -next dosen't get blocked."

Tons of conflicts mostly due to silly include line changes, but mostly
mindless.  A few other small semantic conflicts too, noted from Dave's
pre-merged branch.

Merge tag 'uapi-prep-20121002' of git://git.infradead.org/users/dhowells/linux-headers

Pull preparatory patches for user API disintegration from David Howells:
 "The patches herein prepare for the extraction of the Userspace API
  bits from the various header files named in the Kbuild files.

  New subdirectories are created under either include/uapi/ or
  arch/x/include/uapi/ that correspond to the subdirectory containing
  that file under include/ or arch/x/include/.

  The new subdirs under the uapi/ directory are populated with Kbuild
  files that mostly do nothing at this time.  Further patches will
  disintegrate the headers in each original directory and fill in the
  Kbuild files as they do it.

  These patches also:

   (1) fix up #inclusions of "foo.h" rather than <foo.h>.

   (2) Remove some redundant #includes from the DRM code.

   (3) Make the kernel build infrastructure handle Kbuild files both in
       the old places and the new UAPI place that both specify headers
       to be exported.

   (4) Fix some kernel tools that #include kernel headers during their
       build.

  I have compile tested this with allyesconfig against x86_64,
  allmodconfig against i386 and a scattering of additional defconfigs of
  other arches.  Prepared for main script

268d28371c Merge branch 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-next
This is a major rework of the nouveau driver core, to reflect more closely
how the hw is used and to make it easier to implement newer features now
that the GPUs are more clearly understood than when nouveau started.

It also contains a few other bits:
thermal patches
nv41/44 pcie gart fixes
i2c unregistering fixes.

2f951a5db5 drm/nouveau/therm: add support for fan-control modes
For now, only 2 control modes are available:
- NONE: The fan is never touched (default)
- MANUAL: The fan is set to the user-defined fan speed (pwm1)

This patch introduces a distinction between ptherm internal fan management
and external fan management. The latter is bound to respect the fan mode
while the first can still select the speed it wants unless the NONE mode
is selected. This is important for automatic fan management.

The previous driver waited for 250ms to accumulate data. This version times a
complete fan rotation and extrapolates to RPM.

The fan rotational speed should now be read in less than 250ms (worst case)
and usually in less 50ms.

It looks scary because of the size, but I tried to keep the differences minimal.
Further patches will fix the actual "driver" code and add new features.

v2: change filenames, split to submodules

v3: add a missing include

v4: Ben Skeggs <bskeggs@redhat.com>
- fixed set_defaults() to allow min_duty < 30 (thermal table will
  override this if it's actually necessary)
- fixed set_defaults() to not provide pwm_freq so nv4x (which only has
