This locking path needs proper auditing but probably too late for changes at this point for 2.6.36, so lets go with the quick fix, which is to drop the lock around schedule.

drm_mm: extract check_free_mm_node
I've botched up the range-restriction checks. The result is usually
an X server dying with SIGBUS in libpixman (software fallback rendering).
Change the code to adjust the start and end for range restricted
allocations. IMHO this even makes the code a bit clearer.

The "return" command is buggy on the original nv20, it jumps back to

active bit making the subsequent pushbuf calls fail with a "stack"

When converting this to the new wait_for macro I inverted the wait

When enabling underscan for hdmi monitors, attempt to detect
whether we are driving a TV or a monitor. The should hopefully
prevent underscan from being enabled on monitors attached via
hdmi that do not overscan the image. Only enable underscan
if the mode is a common hdtv mode (480p, 720p, etc.).

We now attempt to free "active" objects following a GPU hang as either
the GPU will be reset or the hang is permenant. In either case, the GPU
writes will not be flushed to main memory and it should be safe to
return that memory back to the system.
The BUG_ON(active) is thus overkill and can erroneously fire after a
EIO.

Waiting for a hard coded 20ms isn't always enough to make sure a vblank
period has actually occurred, so add code to make sure we really have
passed through a vblank period (or that the pipe is off when disabling).
This prevents problems with mode setting and link training, and seems to
fix a bug like https://bugs.freedesktop.org/show_bug.cgi?id=29278, but
on an HP 8440p instead. Hopefully also fixes

If the connector is eDP, it can only be DP, not TMDS.
Always set the detected sink type. If the sink is
detected as non-DP, but there is no EDID, you can still
manually force the port on. If the sink type is DP
and there's no DPCD, there's no way to force the monitor
on since you need both ends to train the link.
