This warning occurs because both lp[0] and target are unsigned, so the

However, the intention was to look at the absolute difference between
the two unsigned quantities. Introduce a small static function to
clarify what we're doing, and call that instead.

Add a comment about a device-driver race condition that could cause the BERI
pipeline to wedge awaiting JTAG in the event that both the low-level console
and the tty layer decide to write to the JTAG FIFO just before JTAG is
disconnected. Resolving this race is a bit tricky as it looks like there
isn't a way to 'give the character back' to the tty layer when we discover
the race. The easy fix is to drop the character, which we don't yet do, but
perhaps should as that is a better outcome than wedging the pipeline.

drm: Take vt(4) default mode from loader tunables
By default, vt(4) gets the "preferred mode" from DRM, when using a DRM

Now, if this mode isn't appropriate, a user can use loader tunables to

1. kern.vt.fb.modes.$connector_name
2. kern.vt.fb.default_mode
For example, to set a 1024x768 mode, no matter the connector:
kern.vt.fb.default_mode="1024x768"
