6911a9b8ae drm/i915: Implement batch and ring buffer dumping
We create a debugfs node (i915_ringbuffer_data) to expose a hex dump
of the ring buffer itself.  We also expose another debugfs node
(i915_ringbuffer_info) with information on the state (i.e. head, tail
addresses) of the ringbuffer.

For batchbuffer dumping, we look at the device's active_list, dumping
each object which has I915_GEM_DOMAIN_COMMAND in its read
domains. This is all exposed through the dri/i915_batchbuffers debugfs
file with a header for each object (giving the objects gtt_offset so
that it can be matched against the offset given in the
BATCH_BUFFER_START command.

8d7773a32d drm/i915: fix up tiling/fence reg setup on i8xx class hw
This fixes all the tiling problems with the 2d ddx. glxgears still doesn't work.
Changes:

- fix a copy&paste error in i8xx fence reg setup. It resulted in an at most a
  512KB offset of the fence reg window, so was only visible sometimes.
- add tests for stride and object size constrains (also for i915 and 1965 class
  hw). Userspace seems to have an of-by-one bug there, which changes the fence
  size by at most 512KB due to an overflow.
- because i8xx hw is quite old (and therefore not as well-tested) I left 2 debug
  WARN_ONs in the i8xx fence reg setup code to hopefully catch any further
  overflows in the bit-fields. Lastly there's one small change to make the
  alignment checks more consistent.

f23c20c83d drm: detect hdmi monitor by hdmi identifier (v3)
Sometime we need to communicate with HDMI monitor by sending audio or video
info frame, so we have to know monitor type. However if user utilize HDMI-DVI adapter to connect DVI monitor, hardware detection will incorrectly show the monitor is HDMI. HDMI spec tell us that any device containing IEEE registration Identifier will be treated as HDMI device.  The patch intends to detect HDMI monitor by this rule.

955a23eb3c drm: Use a little stash on the stack to avoid kmalloc in most DRM ioctls.
The kmalloc was taking up about 1.5% of the CPU on an ioctl-heavy workload
(x11perf -aa10text on 965).  Initial results look like they have a
corresponding improvement in performance for aa10text, but more numbers might
not hurt.
