drivers: gpu: Include appropriate header file in drm_usb.c

Include appropriate header file include/drm/drm_usb.h in drm/drm_usb.c
because functions drm_get_usb_dev(), drm_usb_init() and drm_usb_exit()
have their prototype declarations in the header file.

This eliminates the following warning in drm/drm_usb.c:

drm: store the gem vma offset manager in a typed pointer

This was hidden in a generic void * dev->mm_private. But only ever
used for gem. But thanks to this fake generic pretension no one
noticed that Rob's drm drivers are now all broken.

Merge tag 'vmwgfx-next-2014-01-13' of git://people.freedesktop.org/~thomash/linux into drm-next

Anyway, nothing big here, Three more code cleanup patches from Rashika
Kheria, and one TTM/vmwgfx patch from me that tightens security around TTM
objects enough for them to opened using prime objects from render nodes:

Previously any client could access a shared buffer using the "name", also
without actually opening it. Now a reference is required, and for render nodes
such a reference is intended to only be obtainable using a prime fd.

differences in initial configuration plus setting OCMEM base.
Userspace support is already in upstream mesa.

Note that the existing DT code is simply using the bindings from
downstream android kernel, to simplify porting of this driver to
existing devices.  These do not constitute any committed/stable
DT ABI.  The addition of proper DT bindings will be a subsequent
patch, at which point (as best as possible) I will try to support
either upstream bindings or what is found in downstream android
kernel, so that existing device DT files can be used.

drm/msm: add mdp5/apq8x74

Add support for the new MDP5 display controller block.  The mapping
between parts of the display controller and KMS is:

  plane   -> PIPE{RGBn,VIGn}             \
  crtc    -> LM (layer mixer)            |-> MDP "device"
  encoder -> INTF                        /
  connector -> HDMI/DSI/eDP/etc          --> other device(s)

Unlike MDP4, it appears we can get by with a single encoder, rather
than needing a different implementation for DTV, DSI, etc.  (Ie. the
register interface is same, just different bases.)

Also unlike MDP4, all the IRQs for other blocks (HDMI, DSI, etc) are
routed through MDP.

And finally, MDP5 has this "Shared Memory Pool" (called "SMP"), from
which blocks need to be allocated to the active pipes based on fetch
stride.

drm/msm: add hdmi support for apq8x74/mdp5

The HDMI block is basically the same between older SoC's with mdp4
display controller, and newer ones with mdp5.

So mostly this consists of better abstracting out the different sets of
regulators, clks, etc.  In particular, for regulators and clks we can
split it up by what is needed for hot plug detect to work, and what is
needed to light up the display.

Also, 8x74 has a new phy.. a very simple one, but split out into a
different mmio space.  And with mdp5, the irq is shared with mdp, so we
don't directly register our own irq handler.

drm/msm: add support for non-IOMMU systems

Add a VRAM carveout that is used for systems which do not have an IOMMU.

The VRAM carveout uses CMA.  The arch code must setup a CMA pool for the
device (preferrably in highmem.. a 256m-512m VRAM pool in lowmem is not
cool).  The user can configure the VRAM pool size using msm.vram module
param.

Technically, the abstraction of IOMMU behind msm_mmu is not strictly
needed, but it simplifies the GEM code a bit, and will be useful later
when I add support for a2xx devices with GPUMMU, so I decided to keep
this part.

It appears to be possible to configure the GPU to restrict access to
addresses within the VRAM pool, but this is not done yet.  So for now
the GPU will refuse to load if there is no sort of mmu.  Once address
based limits are supported and tested to confirm that we aren't giving
the GPU access to arbitrary memory, this restriction can be lifted

To avoid a performance loss, make sure the file hash table entries can be
looked up from under an RCU lock, and as a consequence, replace the rwlock
with a spinlock, since we never need to take it in read mode only anymore.

Finally add a ttm object lookup function for the device hash table, that is
intended to be used when we put a ref object on a base object or, in  gem terms,

drm/ttm: Refuse to fault (prime-) imported pages

This is illegal for at least two reasons:

1) While it may work on some platforms / iommus, obtaining page pointers from
mapped sg-lists is illegal, since the DMA API allows page pointer information
to be destroyed in the sg mapping process.

2) TTM has no way of determining the linear kernel map caching state of the
underlying pages. PTEs with conflicting caching state pointing to the same
pfn is not allowed.

TTM operations touching pages of imported sg-tables should be redirected through
the proper dma-buf operations.

VM_PFNMAP is faster than VM_MIXEDMAP due to reduced page administration so
