77c1ff3982 vgaarb: fix incorrect dereference of userspace pointer.
This patch corrects a userspace pointer dereference in the VGA arbiter
in 2.6.32.1.

copy_from_user() is used at line 822 to copy the contents of buf into
kbuf, but a call to strncmp() on line 964 uses buf rather than kbuf.  This
problem led to a GPF in strncmp() when X was started on my x86_32 systems.
 X triggered the behavior with a write of "target PCI:0000:01:00.0" to
/dev/vga_arbiter.

The patch has been tested against 2.6.32.1 and observed to correct the GPF
observed when starting X or manually writing the string "target
PCI:0000:01:00.0" to /dev/vga_arbiter.

84b79f8d28 drm/i915: Fix crash while aborting hibernation
Commit cbda12d77e (drm/i915: implement
new pm ops for i915) introduced the problem that if s2disk hibernation
is aborted, the system will crash, because i915_pm_freeze() does
nothing, while it should at least reverse some operations carried out
by i915_suspend().

Fix this issue by splitting the i915 suspend into a freeze part a
suspend part, where the latter is not executed before creating a
hibernation image, and the i915 resume into a "low-level" resume part
and a thaw part, where the former is not executed after the image has
been created.

b1b87f6b65 drm/i915: untangle page flip completion
When a new page flip is requested, we need to both queue an unpin for
the current framebuffer, and also increment the flip pending count on
the newly submitted buffer.

At flip finish time, we need to unpin the old fb and decrement the flip
pending count on the new buffer.

The old code was conflating the two, and led to hangs when new direct
rendered apps were started, replacing the existing frame buffer.  This
patch splits out the buffers and prevents the hangs.

fd2e8ea597 drm/i915: Increase fb alignment to 64k
An untiled framebuffer must be aligned to 64k. This is normally handled
by intel_pin_and_fence_fb_obj(), but the intelfb_create() likes to be
different and do the pinning itself. However, it aligns the buffer
object incorrectly for pre-i965 chipsets causing a PGTBL_ERR when it is
installed onto the output.

99fcb766a3 drm/i915: Update write_domains on active list after flush.
Before changing the status of a buffer with a pending write we will await
upon a new flush for that buffer. So we can take advantage of any flushes
posted whilst the buffer is active and pending processing by the GPU, by
clearing its write_domain and updating its last_rendering_seqno -- thus
saving a potential flush in deep queues and improves flushing behaviour
upon eviction for both GTT space and fences.

In order to reduce the time spent searching the active list for matching
write_domains, we move those to a separate list whose elements are
the buffers belong to the active/flushing list with pending writes.

Orignal patch by Chris Wilson <chris@chris-wilson.co.uk>, forward-ported
by me.

In addition to better performance, this also fixes a real bug. Before
this changes, i915_gem_evict_everything didn't work as advertised. When
the gpu was actually busy and processing request, the flush and subsequent
wait would not move active and dirty buffers to the inactive list, but
just to the flushing list. Which triggered the BUG_ON at the end of this
function. With the more tight dirty buffer tracking, all currently busy and
dirty buffers get moved to the inactive list by one i915_gem_flush operation.

I've left the BUG_ON I've used to prove this in there.

b91ad0ec52 drm/i915: Rework DPLL calculation parameters for Ironlake
Got Ironlake DPLL parameter table, which reflects the hardware
optimized values. So this one trys to list DPLL parameters for
different output types, should potential fix clock issue seen
on new Arrandale CPUs.

This fixes DPLL setting failure on one 1920x1080 dual channel
LVDS for Ironlake. Test has also been made on LVDS panels with
smaller size and CRT/HDMI/DP ports for different monitors on
their all supported modes.

Update:
- Change name of double LVDS to dual LVDS.
- Fix SSC 120M reference clock to use the right range.
