When trying to set other display mode besides the fixed panel mode, the
panel fitting should be enabled. This is similar to LVDS.

This makes them sort to the front in X, which makes them likely to be

Move the common routines into separate functions to not only increase
readability, but also throwaway surplus code.
In doing so, we review the calculation of the aspect preserving scaling
and avoid the use of fixed-point until we need to calculate the accurate
scale factor.
v2: Improve comments as suggested by Jesse.

The original i965, including the revised G35 and Q35, requires an
alignment of 128K for the display surface with linear memory, so
increase the requirement from 64k for these chipsets. For the later
chipsets in the i965 family, only a 4k alignment is required. (So
long as we do not start performing asynchronous flips.)
Note the impact of this should be slight as on i965 we should be using a
tiled frontbuffer for anything up to a 4096x4096 display.
v2: compilation fixes and note that the docs do not exclude the G35 from
the extra alignment.

Unmask the bits for link training reporting before starting link
training. If stage 1 training finished before we unmask them, then we'd
spin around in a loop a few times until smashing on through. Which is
harmless, since training _did_ succeed, it just looks ugly in dmesg.

NUM_TV_MODES is the same as ARRAY_SIZE(tv_modes). In the end, I
decided it was cleaner to remove NUM_TV_MODES and just use
ARRAY_SIZE(tv_modes) through out.

We generally issue an error message at the point of failure, and so this
warning with a fairly pointless stacktrace is superfluous and ugly.
Needless to say, the common trigger for this WARN happens to be EIO
where this is pure noise.

Since mode->clock is in kHz we should be checking against 2700000
instead of just 27000. This patch gets my x201s working again (well
working as well as it ever was anyway).
When looking for this I also noticed we set link_bw to 270000, but the
calculation is different. Does it also need to use kHz or we using
10kHz internally?

If we were not able to map the io bar in device init, don't attempt
to unmap it in device fini. All radeons should have a io bar, so
I doubt this would ever trigger, but just to be on the safe side...

This interface allows userspace to request hyperz support, it probably
needs more locking, and really reporting that you can have hyperz is racy
since someone else might get it before you do.
v2: modify so we pass 0 valued packets to let DDX/r300c keep working.
also fixed incorrect 0x4f1c reference.
v3: fixup zb_bw_cntl so older drivers keep working
v4: add locking, fixup SC_HYPERZ_EN - patch stream to disable hiz

This migrates a bunch of DRM_DEBUG->DRM_DEBUG_KMS so we can get more modesetting related info without all the other ioctl handling easily.
Also the PM code moves to DRM_DEBUG_DRIVER mostly.

set_current_state() is called only once before the first iteration.
After return from schedule_timeout() current state is TASK_RUNNING. If
we are going to wait again, set_current_state() must be called.
