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.

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.

Note AMD dropped SSE5 extensions in order to avoid ISA overlap with Intel
AVX instructions. The SSE5 bit was recycled as XOP extended instruction
bit, CVT16 was deprecated in favor of F16C (half-precision float conversion
instructions for AVX), and the remaining FMA4 (4-operand FMA instructions)
gained a separate CPUID bit. Replace non-existent references with today's
CPUID specifications.

When supported by hardware, this allows to control per-port activity, locate
and fault LEDs via the led(4) API for localization and status reporting
purposes. Supporting AHCI controllers may transmit that information to the
backplane controllers via SGPIO interface. Backplane controllers interpret
received statuses in some way (IBPI standard) to report them using present
indicators.
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.
