280bcab3d0 drm2: a few minor fixes after r280183
* 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).

455fa6518a drm: Update the device-independent code to match 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.

47671d1bab An update for the i915 GPU driver, which brings the code up to Linux
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.

e27f871969 Add the code for new Intel GPU driver, which supports GEM, KMS and
works with new generations of GPUs (IronLake, SandyBridge and
supposedly IvyBridge).

The driver is not connected to the build yet.
