[Intel-gfx] [PATCH v4 00/17] Pre-calculate SKL-style atomicwatermarks

[Matt Roper]

For a detailed explanation of this series, please see the original cover letter:
  https://lists.freedesktop.org/archives/intel-gfx/2016-April/091293.html

This version is pretty much the same as v3 except that it should also fix the
problems that appear if the BIOS programs bogus/unexpected DDB values before
the driver starts up.  Aside from rebasing to the latest -nightly, the only
only changes this time around are the addition of patch #8 (track whether we
consider the DDB to be in a sane state or not) and modifications to patch #9 to
force a full DDB recompute if the flag is set.

Sorry for the delay getting this out; I've been out of office for the last two
weeks (no access to hardware) and just got back today.
