453a7d46dc drm: remove root requirement from DRM_IOCTL_SET_VERSION (+ DRM_IOCTL_AUTH_MAGIC)
Just a DRM_MASTER flag is sufficient here, though maybe this call is
totally deprecated anyway (xf86-video-intel still calls it though).

(airlied: drop ioctl auth_magic as discussed on mailing list also)

38d5487db7 drm: When adding probed modes, preserve duplicate mode types
The code which takes probed modes and adds them to a connector eliminates
duplicate modes by comparing them using drm_mode_equal. That function
doesn't consider the type bits, which means that any modes which differ only
in the type field will be lost.

One of the bits in the mode->type field is the DRM_MODE_TYPE_PREFERRED bit.
If the mode with that bit is lost, then higher level code will not know
which mode to select, causing a random mode to be used instead.

This patch simply merges the two mode type bits together; that seems
reasonable to me, but perhaps only a subset of the bits should be used? None
of these can be user defined as they all come from looking at just the
hardware.

f360132626 drm/i915: fix 845G FIFO size & burst length
I had one report of flicker due to FIFO underruns on 845G.  Scott was
kind enough to test a few patches and report success with this one.
Looks like 845G measures FIFO size slightly differently than other
chips, and we were also clobbering the FIFO burst length.  Fixing both
of those issues gives him a healthy machine again.

Note that we still only adjust plane A's watermark in the 830/845
case.  If someone is willing to test we could support a bigger variety
of dual-head 830/845 configurations with a bit more code.

Fixes fdo bug #19304 (again).
