Merge tag 'v3.5-rc4' into drm-intel-next-queued

I want to merge the "no more fake agp on gen6+" patches into
drm-intel-next (well, the last pieces). But a patch in 3.5-rc4 also
adds a new use of dev->agp. Hence the backmarge to sort this out, for
otherwise drm-intel-next merged into Linus' tree would conflict in the
relevant code, things would compile but nicely OOPS at driver load :(

Conflicts in this merge are just simple cases of "both branches
changed/added lines at the same place". The only tricky part is to
keep the order correct wrt the unwind code in case of errors in
intel_ringbuffer.c (and the MI_DISPLAY_FLIP #defines in i915_reg.h
together, obviously).

Conflicts:
	drivers/gpu/drm/i915/i915_reg.h
	drivers/gpu/drm/i915/intel_ringbuffer.c

14be93ddff drm/i915 + agp/intel-gtt: prep work for direct setup
To be able to directly set up the intel-gtt code from drm/i915 and
avoid setting up the fake-agp driver we need to prepare a few things:
- pass both the bridge and gpu pci_dev to the probe function and add
  code to handle the gpu pdev both being present (for drm/i915) and
  not present (fake agp).
- add refcounting to the remove function so that unloading drm/i915
  doesn't kill the fake agp driver

v2: Fix up the cleanup and refcount, noticed by Jani Nikula.

effbc4fd8e Merge branch 'drm-intel-next' of git://people.freedesktop.org/~danvet/drm-intel into drm-core-next
Daniel Vetter wrote
First pull request for 3.5-next, slightly large than usual because new
things kept coming in since the last pull for 3.4.
Highlights:
- first batch of hw enablement for vlv (Jesse et al) and hsw (Eugeni). pci
 ids are not yet added, and there's still quite a few patches to merge
 (mostly modesetting). To make QA easier I've decided to merge this stuff
 in pieces.
- loads of cleanups and prep patches spurred by the above. Especially vlv
 is a real frankenstein chip, but also hsw is stretching our driver's
 code design. Expect more to come in this area for 3.5.
- more gmbus fixes, cleanups and improvements by Daniel Kurtz. Again,
 there are more patches needed (and some already queued up), but I wanted
 to split this a bit for better testing.
- pwrite/pread rework and retuning. This series has been in the works for
 a few months already and a lot of i-g-t tests have been created for it.
 Now it's finally ready to be merged.  Note that one patch in this series
 touches include/pagemap.h, that patch is acked-by akpm.
- reduce mappable pressure and relocation throughput improvements from
 Chris.
- mmap offset exhaustion mitigation by Chris Wilson.
- a start at figuring out which codepaths in our messy dri1/ums+gem/kms
 driver we actually need to support by bailing out of unsupported case.
 The driver now refuses to load without kms on gen6+ and disallows a few
 ioctls that userspace never used in certain cases. More of this will
 definitely come.
- More decoupling of global gtt and ppgtt.
- Improved dual-link lvds detection by Takashi Iwai.
- Shut up the compiler + plus fix the fallout (Ben)
- Inverted panel brightness handling (mostly Acer manages to break things
 in this way).
- Small fixlets and adjustements and some minor things to help debugging.

Regression-wise QA reported quite a few issues on ivb, but all of them
turned out to be hw stability issues which are already fixed in
drm-intel-fixes (QA runs the nightly regression tests on -next alone,
without -fixes automatically merged in). There's still one issue open on
snb, it looks like occlusion query writes are not quite as cache coherent
as we've expected. With some of the pwrite adjustements we can now
reliably hit this. Kernel workaround for it is in the works."

Flush the chipset write buffers before and after adjusting the GTT base

there are always those persistent PGTBL_ER that keep getting reported
upon resume.

201728429d intel-gtt: maximize ggtt size on platforms that support this
On VT-d supporting platforms the GGTT is allocated in a stolen mem
section separate from graphcis stolen mem. The GMCH register contains
a bitfield specifying the size of that region. Docs suggest that this
region can only be used for GGTT and PPGTT. Hence ensure that the
PPGTT is disabled and use the complete area for the GGTT.

Unfortunately the graphics core on G33/Pineview can't cope with really
large GTTs and the BIOS usually enables the maximum of 512MB. So
don't bother with maximizing the GTT on these platforms.

1a997ff2a0 intel-gtt: introduce intel_gtt_driver
Same idea as INTEL_INFO from drm/i915. This
- reduces the dependancy on agp_driver
- stops the what-does-IS_I965G-mean confusion (here it's just gen4, in
  drm/i915 it's gen >=4)
- further prepares the separation of the fake agp driver from the rest.

e2404e7c3f agp/intel: make intel-gtt.c into a real source file
Now that the disentangling is complete, stop including intel-gtt.c
from intel-agp.c.

The linux build system _really_ doesn't allow .c source files with the
same name as the module. It fails with the following message when trying
to build such a bugger:

make[3]: Circular drivers/char/agp/intel-agp.o <- drivers/char/agp/intel-agp.o dependency dropped.

Instead of renameing intel-agp.c I've simply created a new module out
of intel-gtt.c. Renaming intel-agp.ko to something else is not an option
for it will surely kill someones boot process.

This also paves the way to use the gtt code without loading the agp
driver.
