Pull drm updates from Dave Airlie:
 "I Was Almost Tempted To Capitalise Every Word, but then I decided I
  couldn't read it myself!

  I've also got one pull request for the sti driver outstanding.  It
  relied on a commit in Greg's tree and I didn't find out in time, that
  commit is in your tree now so I might send that along once this is
  merged.

  I also had the accidental misfortune to have access to a Skylake on my
  desk for a few days, and I've had to encourage Intel to try harder,
  which seems to be happening now.

  Here is the main drm-next pull request for 4.4.

  Highlights:

  New driver:
        vc4 driver for the Rasberry Pi VPU.
        (From Eric Anholt at Broadcom.)

DRM is a lot more than a direct rendering manager nowadays, and there's
also a bunch of things worth documenting for gpu driver developers
outside of drivers/gpu/drm, like vgaarb, vga_switcheroo or the various
hardware buses like host1x and ipu-v3.

To avoid further confusion let's rename the top-level to reflect
reality.

And yes I'm already looking forward to when we need to replace the G
in GPU with a * ;-)

Inspired by a thread with Lukas since he refused to include the
vga_switcheroo docs into the drm docs because it's not drm.

Currently the encoding of documents generated by DocBook depends on
the current locale.  Make the output reproducible independently of
the locale, by setting the encoding to UTF-8 (LC_CTYPE=C.UTF-8) by
preference, or ASCII (LC_CTYPE=C) as a fallback.

LC_CTYPE can normally be overridden by LC_ALL, but the top-level
Makefile unsets that.

Pull documentation updates from Jonathan Corbet:
 "There's been a fair amount going on in the docs tree this time around,
  including:

   - Support for reproducible document builds, from Ben Hutchings and
     company.

   - The ability to automatically generate cross-reference links within
     a single DocBook book and embedded descriptions for large
     structures.  From Danilo Cesar Lemes de Paula.

   - A new document on how to add a system call from David Drysdale.

   - Chameleon bus documentation from Johannes Thumshirn.

Functions, Structs and Parameters definitions on kernel documentation
are pure cosmetic, it only highlights the element.

To ease the navigation in the documentation we should use <links> inside
those tags so readers can easily jump between methods directly.

This was discussed in 2014[1] and is implemented by getting a list
of <refentries> from the DocBook XML to generate a database. Then it looks
for <function>,<structnames> and <paramdef> tags that matches the ones in
the database. As it only links existent references, no broken links are
added.

Some kernel-doc sections are included in multiple DocBook files.  This
means the mandocs target will generate the same manual page multiple
times with different metadata (author name/address and manual title,
taken from the including DocBook file).  If it's invoked in a parallel
build, the output is non-determinstic.

Build the manual pages in a separate subdirectory per DocBook file,
then sort and de-duplicate when installing them (which is serialised).

  As part of the reproducible builds project, Jérémy Bobbio identified
  several time-dependent and non-deterministic functions in the document
  build process (htmldocs, mandocs targets).  This patch series should fix
  all of those.

I ended up reverting one patch that introduced problems.

This reverts commit b44158b17099ed5c7c8f4bfb7029942adbfbc318.  This commit
introduced warnings and possibly inconsistent results into the doc build
process.  The goal is good but it will need to be achieved another way.
