Before, the font was loaded and the window size recalculated, giving an
unusable terminal, even if the actual font didn't change.

This fix a race where the threads waiting for the bus would wake up early
and still see bus as busy.
While here, give a better description to wmesg for the two use cases we
have (bus and io waiting).

will now find the virtual to physical mapping for libkvm to use at
runtime. This makes PHYSADDR redundant, however keep it around to give
everyone a chance to update their libkvm.

physaddr. This should allow for a kernel where PHYSADDR and KERNPHYSADDR
are both undefined.
For now libkvm will use the old method of reading physaddr and kernaddr
to allow it to work with old kernels. This could be removed in the future
when enough time has passed.

bus_new_pass() handler so it doesn't happen until BUS_PASS_CPU. This allows
the anatop driver to outbid the generic simplebus driver (which the FDT
data describes as compatible).
Some day when we handle power regulators, this driver may actually
become a functional simplebus and attach the regulators as children, as
described in the FDT data.
Increasingly, FDT data has the "simple-bus" compatible string on nodes
that have children, but we wouldn't consider them to be busses. If the
node lacks a ranges property then we will fail to attach successfully,
so fail to probe as well.
rather than u_char.
To try and play nice with the ABI, the u_char CPU ID values are clamped
at 254. The new fields now contain the full CPU ID, or -1 for no cpu.

lose the contents of consecutive writes (that happens within two SD card
clock cycles).
This fixes the causes of instability during the SD card detection and
identification on Raspberry Pi (which happens at 400 kHz and so was much
more vulnerable to this issue).
Remove the previous workaround which clearly can't provide the same effect.

The TI watchdog timer is present on BeagleBone's. Since 2014, U-Boot
has been booting the BeagleBone with the watchdog enabled. We need to
disable it on boot to avoid a spurious reset.
The timer isn't exactly precise, but it will do as a watchdog. This
is also a reflection of the watchdog(9) API.
In the future, we could handle interrupts, but the watchdog(9) API
needs to be a bit smarter before that can happen.
