v2: Add locking to unmap, noticed by Chris Wilson. Note that even
though we call unmap with our own dev->struct_mutex held that won't
result in an immediate deadlock since we never go through the dma_buf
interfaces for our own, reimported buffers. But it's still easy to
blow up and anger lockdep, but that's already the case with our ->map
implementation. Fixing this for real will involve per dma-buf ww mutex
locking by the callers. And lots of fun. So go with the duct-tape
approach for now.

After any "soft gfx reset" we must manually invalidate the TLBs
associated with each ring. Empirically, it seems that a
suspend/resume or D3-D0 cycle count as a "soft reset". The symptom is
that the hardware would fail to note the new address for its status
page, and so it would continue to write the shadow registers and
breadcrumbs into the old physical address (now used by something
completely different, scary). Whereas the driver would read the new
status page and never see any progress, it would appear that the GPU
hung immediately upon resume.

If we get an error event really early in the driver setup sequence,
which gen3 is especially prone to with various display GTT faults we
Oops. So try to avoid this.

Additionally with Haswell the transcoders are a separate bank of
registers from the pipes (4 transcoders, 3 pipes). In event of an
error, we want to be sure we have a complete and accurate picture of
the machine state, so record all the transcoders in addition to all
the active pipes.

This regression has been introduced in

    drm/i915: convert PIPECONF to use transcoder instead of pipe

Based on the patch "drm/i915: Dump all transcoder registers on error"
from Chris Wilson:

v2: Rebase so that we don't try to be clever and try to figure out the
cpu transcoder from hw state. That exercise should be done when we
analyze the error state offline.

The actual bugfix is to not call intel_pipe_to_cpu_transcoder in the
error state capture code in case the pipes aren't fully set up yet.

v3: Simplifiy the err->num_transcoders computation a bit. While at it
make the error capture stuff save on systems without a display block.

v4: Fix fail, spotted by Jani.

v5: Completely new commit message, cc: stable.

It takes an unsigned value. This happens not to blow up on 64-bit

drm_calc_vbltimestamp_from_scanoutpos() to calculate totally bogus

hang after a DPMS off cycle with current xf86-video-ati Git.
