The exynos drm driver used a specific ioctl - DRM_EXYNOS_PLANE_SET_ZPOS
to set zpos of plane. It can be substitute to property of plane. This
patch adds a property for plane zpos and removes
DRM_EXYNOS_PLANE_SET_ZPOS ioctl.

Userspace uses long in quite a few places more than the kernel. Which
gives me neat proof that I'm the only guy on this side of the galaxy
who ever tried to run glxgears on a 64bit machine with sis graphics on
linux.
Note that the longs in drm_sis_mem_t aren't aligned properly, so this
won't even work with 32bit userspace on 64bit kernel as-is. Hence the
patch can't break that, either.
Nope, I'm not nuts enough to write the 32bit ioctl compat layer for
this and test it with some wine app. Even though hunting the ebay
dungeons for a sis card actually supported by the mesa drivers casts
some doubts on this ...

In order to support snoopable memory on non-LLC architectures (so that
we can bind vgem objects into the i915 GATT for example), we have to
avoid the prefetcher on the GPU from crossing memory domains and so
prevent allocation of a snoopable PTE immediately following an uncached
PTE. To do that, we need to extend the range allocator with support for
tracking and segregating different node colours.
This will be used by i915 to segregate memory domains within the GTT.
v2: Now with more drm_mm helpers and less driver interference.

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).

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

Before Kernel 3.5, no one was checking for the return value of
drm_connector_attach_property, so we never noticed that we were unable
to create some properties. Commit "drm: WARN() when
drm_connector_attach_property fails" added a WARN when we fail to
create a property, and the transition from "connector properties" to
"object properties" changed the warning message a little bit.
On i915 machines with many TV connectors we hit the maximum number of
properties (since each TV connector uses a lot of properties), so we
get a few backtraces in our logs. This commit increases the maximum
number of properties to 24 hoping we'll have enough room for
everybody.
Chris suggested that we convert this code to "lists", but I believe
this conversion can come after we make sure people's dmesgs are not
spammed by our driver.

Change the ns_timeout parameter of the wait ioctl to a signed value.
Doing this allows the kernel to provide an infinite wait when a timeout
of less than 0 is provided. This mimics select/poll.
Initially the parameter was meant to match up with the GL spec 1:1, but
after being made aware of how much 2^64 - 1 nanoseconds actually is, I
do not think anyone will ever notice the loss of 1 bit.
The infinite timeout on waiting is similar to the existing i915
userspace interface with the exception that struct_mutex is dropped
while doing the wait in this ioctl.

ULONG_MAX is often used to check for integer overflow when calculating
allocation size. While ULONG_MAX happens to work on most systems, there
is no guarantee that `size_t' must be the same size as `long'.
This patch introduces SIZE_MAX, the maximum value of `size_t', to improve
portability and readability for allocation size validation.

This helps implement GL_ARB_sync but stops short of allowing full blown
sync objects. Finally we can use the new timed seqno waiting function
to allow userspace to wait on a buffer object with a timeout. This
implements that interface.
The IOCTL will take as input a buffer object handle, and a timeout in
nanoseconds (flags is currently optional but will likely be used for
permutations of flush operations). Users may specify 0 nanoseconds to
instantly check.
The wait ioctl with a timeout of 0 reimplements the busy ioctl. With any
non-zero timeout parameter the wait ioctl will wait for the given number
of nanoseconds on an object becoming unbusy. Since the wait itself does
so holding struct_mutex the object may become re-busied before this
completes. A similar but shorter race condition exists in the busy
ioctl.

Changelog v3:
- use __u64 instead of pointer in ioctl struct.
The G2D is a 2D graphic accelerator that supports Bit Block Transfer.
This G2D driver is exynos drm specific and supports only G2D(version
4.1) of later Exynos series from Exynos4X12 because supporting DMA.
The G2D is performed by two tasks simply.
1. Configures the rendering parameters, such as foreground color and
coordinates data by setting the drawing context registers.
2. Start the rendering process by setting thre relevant command
registers accordingly.
The G2D version 4.1 supports DMA mode as host interface. User can make
command list to reduce HOST(ARM) loads. The contents of The command list
is setted to relevant registers of G2D by DMA.
The command list is composed Header and command sets and Tail.
- Header: The number of command set(4Bytes)
- Command set: Register offset(4Bytes) + Register data(4Bytes)
- Tail: Pointer of base address of the other command list(4Bytes)
By Tail field, the G2D can process many command lists without halt at
one go.
The G2D has following the rendering pipeline.
--> Primitive Drawing --> Rotation --> Clipping --> Bilinear Sampling
--> Color Key --> ROP --> Mask Operation --> Alpha Blending -->
Dithering --> FrameBuffer
And supports various operations from the rendering pipeline.
- copy
- fast solid color fill
- window clipping
- rotation
- flip
- 4 operand raster operation(ROP4)
- masking operation
- alpha blending
- color key
- dithering
- etc
User should make the command list to data and registers needed by
operation to use. The Exynos G2D driver only manages the command lists
received from user. Some registers needs memory base address(physical
address) of image. User doesn't know its physical address, so fills the
gem handle of that memory than address to command sets, then G2D driver
converts it to memory base address.
We adds three ioctls and one event for Exynos G2D.
- ioctls
DRM_EXYNOS_G2D_GET_VER: get the G2D hardware version
DRM_EXYNOS_G2D_SET_CMDLIST: set the command list from user to driver
DRM_EXYNOS_G2D_EXEC: execute the command lists setted to driver
- event
DRM_EXYNOS_G2D_EVENT: event to give notification completion of the
command list to user

Also return void instead of int. We have more than 100 callers and
no one checks for the return value.
If this function fails the property won't be exposed by the get/set
