83d45f234d 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.

9baa3c34ac PCI: Remove DEFINE_PCI_DEVICE_TABLE macro use
We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to
meet kernel coding style guidelines.  This issue was reported by checkpatch.

A simplified version of the semantic patch that makes this change is as
follows (http://coccinelle.lip6.fr/):

// <smpl>

@@
identifier i;
declarer name DEFINE_PCI_DEVICE_TABLE;
initializer z;
@@

- DEFINE_PCI_DEVICE_TABLE(i)

9138475862 Merge branch 'linux-3.17' of git://anongit.freedesktop.org/git/nouveau/linux-2.6
Pull nouveau drm updates from Ben Skeggs:
 "Apologies for not getting this done in time for Dave's drm-next merge
  window.  As he mentioned, a pre-existing bug reared its head a lot
  more obviously after this lot of changes.  It took quite a bit of time
  to track it down.  In any case, Dave suggested I try my luck by
  sending directly to you this time.

  Overview:

   - more code for Tegra GK20A from NVIDIA - probing, reclockig
   - better fix for Kepler GPUs that have the graphics engine powered
     off on startup, method courtesy of info provided by NVIDIA
   - unhardcoding of a bunch of graphics engine setup on
     Fermi/Kepler/Maxwell, will hopefully solve some issues people have
     noticed on higher-end models
   - support for "Zero Bandwidth Clear" on Fermi/Kepler/Maxwell, needs
     userspace support in general, but some lucky apps will benefit
     automagically
   - reviewed/exposed the full object APIs to userspace (finally), gives
     it access to perfctrs, ZBC controls, various events.  More to come
     in the future.
   - various other fixes"

d6bd380373 drm/gf100-/gr: implement the proper SetShaderExceptions method
We have another version of it implemented in SW, however, that version
isn't serialised with normal PGRAPH operation and can possibly clobber
the enables for another context.

This is the same method that's implemented by the NVIDIA binary driver.

6c6ae061b6 drm/nouveau/fifo: allow direct access to channel control registers where possible
The indirect method has been left in-place here as a fallback path, as
it may not be possible to map the non-PAGE_SIZE aligned control areas
across some chipset+interface combinations.

This isn't a problem for the primary use-case where the core and drm
are linked together in kernel-land, but across a VM or (in the case
where it applies now) between the core in the kernel and a userspace
test tool.
