Pineview with DDR3 memory has different latencies to enable CxSR.
This patch updates CxSR latency table to add Pineview DDR3 latency
configuration. It also adds one flag "is_ddr3" for checking DDR3
setting in MCHBAR.

We can, by virtue of a vblank interrupt firing in the middle of setting
up the unpin work (i.e. after we set the unpin_work field and before we
write to the ringbuffer) enter intel_finish_page_flip() prior to
receiving the pending flip notification. Therefore we can expect to hit
intel_finish_page_flip() under normal circumstances without a pending flip
and even without installing the pending_flip_obj. This is exacerbated by
aperture thrashing whilst binding the framebuffer

Bug 15733 - Crash when accessing nonexistent GTT entries in i915
https://bugzilla.kernel.org/show_bug.cgi?id=15733
On G33 and above, the size of the GTT space is determined by the GMCH
control register. Prior to this revision, the size is determined by the
size of the aperture. So we must careful to map and fill the appropriate
range depending on chipset.

Add power monitoring support to the i915 driver for use by the IPS

This doesn't change the clock limits (minimums), i.e. it won't make it
output 720x576 PAL nor 720x480 NTSC, but it will work with modes like
1080i etc. (including GLX and textured Xvideo, not sure about the
overlay).
Tested on i915 + analog VGA, it would be worth checking if newer chips
(and which ones) still support interlaced mode.

The BSD (bit stream decoder) ring is used for accessing the BSD engine
which decodes video bitstream for H.264 and VC1 on G45+. It is
asynchronous with the render ring and has access to separate parts of
the GPU from it, though the render cache is coherent between the two.

The active list and request list move into the ringbuffer structure,
so each can track its active objects in the order they are in that
ring. The flushing list does not, as it doesn't matter which ring
caused data to end up in the render cache. Objects gain a pointer to
the ring they are active on (if any).

Some of the qib sysfs code passes a buffer pointer into
simple_read_from_buffer() but relies on a function call in another
parameter of the same call to initialize that pointer. Since the order
of evaluation of function parameters is undefined, this will break if
gcc chooses the wrong order.
Fix this by splitting the code into two separate function calls.
This was noticed because of warnings like the following on ppc:
drivers/infiniband/hw/qib/qib_fs.c: In function 'portcntrs_2_read':
drivers/infiniband/hw/qib/qib_fs.c:203: warning: 'counters' is used uninitialized in this function

This is preparation for supporting multiple ringbuffers on Ironlake.
The non-copy-and-paste changes are:
- de-staticing functions
- I915_GEM_GPU_DOMAINS moving to i915_drv.h to be used by both files.
- i915_gem_add_request had only half its implementation
copy-and-pasted out of the middle of it.
This reverts commit 663cb47cc2.
This patch was merged out of the proper order, so instead of fixing a
problem with a prior (unmerged) patch, it creates one. Ooops!

Reserve_memtype will allocate memory for new memtype, but
in free_memtype, after the memtype erased from rbtree, the
memory is not freed.
Changes since V1:
make rbt_memtype_erase return erased memtype so that
it can be freed in free_memtype.
