Datasheet says vge(4) controllers support DAC but it seems that's
not true on old PCI based controllers. DAC configuration is read
from EEPROM in device reset phase and driver can override DAC
configuration. However I guess there is an undocumented reason why
EEPROM configuration does not enable DAC so do not blindly override
DAC configuration. Recent PCIe based controllers are supposed to
support 64bit DMA so allow 64bit DMA only on PCIe based controllers.

sh: Allow terminating a heredoc with a terminator at EOF without a newline.
This is sometimes used with eval or old-style command substitution, and most
shells other than ash derivatives allow it.
It can also be used with scripts that violate POSIX's requirement on the
application that they end in a newline (scripts must be text files except
that line length is unlimited).
Example:
v=`cat <<EOF
foo
EOF`
echo $v
This commit does not add support for the similar construct with new-style
command substitution, like
v=$(cat <<EOF
foo
EOF)
This continues to require a newline after the terminator.

usb: change to one-pass probing of device drivers
This brings USB bus more in line with how newbus is supposed to be used.
Also, because of the two-pass probing the following message was produced
by devd in default configuration when almost any USB device was
connected:
Unknown USB device: vendor <> product <> bus <>
This should be fixed now.
Note that many USB device drivers pass some information from probe
method to attach method via ivars. For this to continue working we rely
on the fact that the subr_bus code calls probe method of a winning driver
again before calling its attach method in the case where multiple
drivers claim to support a device. This is done because device
description is set in successful probe methods and we want to get a correct
device description from a winning driver. So now this logic is re-used
for setting ivars too.

Fix a race in the SMP rendezvous code. Specifically, the write by the
last CPU to to finish the rendezvous action may become visible to
different CPUs at different times. As a result, the CPU that initiated
the rendezvous may exit the rendezvous and drop the lock allowing another
rendezvous to be initiated on the same CPU or a different CPU. In that
case the exit sentinel may be cleared before all CPUs have noticed causing
those CPUs to hang forever.
Workaround this by using a generation count to notice when this race
occurs and to exit the rendezvous in that case.
