This update brings few features:
o Support for the setmaster/dropmaster ioctls. For instance, they
are used to run multiple X servers simultaneously.
o Support for minor devices. The only user-visible change is a new
entry in /dev/dri but it is useless at the moment. This is a
first step to support render nodes [1].
The main benefit is to greatly reduce the diff with Linux (at the
expense of an unreadable commit diff). Hopefully, next upgrades will be
easier.
No updates were made to the drivers, beside adapting them to API
changes.

In C mode -fms-extensions option enables anonymous structs and unions,
allowing us to use this C11 feature in kernel. Of course, clang supports
it without any extra options.

Biggest update is the rewrite of the i915 gem io to more closely
follow Linux model, althought the mechanism used by FreeBSD port is
different.

Also, always use -Wno-unknown-pragma to (hopefully temporarily) work
around #pragma ident in debug.h in the opensolaris code. Remove some
stale warning suppression that's no longer necessary.
This feature is required by Mesa 9.2+. Without this, a GL application
crashes with the following message:
# glxinfo

Gen6+ requires Kernel 3.6 or later.

Now, Mesa 10.2.4 and 10.3-rc3 works fine:

options into kern.opts.mk and change all the places where we use
src.opts.mk to pull in the options. Conditionally define SYSDIR and
use SYSDIR/conf/kern.opts.mk instead of a CURDIR path. Replace all
instances of CURDIR/../../etc with STSDIR, but only in the affected
files.
As a special compatibility hack, include bsd.owm.mk at the top of
kern.opts.mk to allow the bare build of sys/modules to work on older
systems. If the defaults ever change between 9.x, 10.x and current for
these options, however, you'll wind up with the host OS' defaults
rather than the -current defaults. This hack will be removed when
we no longer need to support this build scenario.

This driver is based on Linux 3.8 and a previous effort by kan@.
More informations about this project can be found on the FreeBSD wiki:
https://wiki.freebsd.org/AMD_GPU
The driver is split into:
sys/dev/drm2:
The driver sources.
sys/modules/drm2/radeonkmw:
The driver main kernel module's Makefile.
sys/modules/drm2/radeonkmsfw:
All firmware kernel module Makefiles. There's one directory and one
Makefile for each firmware.
sys/contrib/dev/drm2/radeonkmsfw:
All firmware binary sources.
tools/tools/drm/radeon
Tools to update firmwares or regenerate some headers.
Merging the driver to FreeBSD 9.x may be possible but not a priority for
now.
