* Remove obsolete drm_agp_*_memory() prototypes.
* Fix comment in drm_fops.c (outisde -> outside).
* Fix some formatting issues in drm_stub.c (spaces -> tabs).
* Add missing case statement (gen == 3) in intel_gpu_reset().
* Restore pci_enable_busmaster() call in the init path (fixes gpu hang on i945GM).
* Replace M_WAITOK with M_NOWAIT when the return value of malloc is checked (may be incorrect).

While here update the list of devices id to match the one in linux 3.8.13

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.

commit 4d93914ae3db4a897ead4b. Some related drm infrastructure
changes are imported as needed.
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.

This feature is required by Mesa 9.2+. Without this, a GL application
crashes with the following message:
# glxinfo
name of display: :0.0
Gen6+ requires Kernel 3.6 or later.
Assertion failed: (ctx->Version > 0), function handle_first_current,
file ../../src/mesa/main/context.c, line 1498.
Abort (core dumped)
Now, Mesa 10.2.4 and 10.3-rc3 works fine:
# glxinfo
name of display: :0
display: :0 screen: 0
direct rendering: Yes

OpenGL renderer string: Mesa DRI Intel(R) 965GM

The code was imported from Linux 3.8.13.

already. Also, according to the specs, GDRST register is not in the
power well, so the forcewake for reset status read is excessive for
this reason.
Use plain register read for waiting of the reset completion
notification, to avoid gt_lock recursion. Linux upstream did the
similar change, but their code was already restructured.

supposedly IvyBridge).
The driver is not connected to the build yet.
