The main changes are:
1. Use of multiple bus dma tags.
2. Timing of CAM requests by the driver.
3, Firmware interface change relating to retrieving AEN's.
4. Removal of twa_intrhook.
5. Bundling of latest firmware with BBU capability.

a 82557 chipset, and they want to use the 82503.

- Mark mount, unmount and nmount MPSAFE.
- Add a stub for _umtx_op().
- Mark open(), link(), unlink(), and freebsd32_sigaction() MPSAFE.
Pointy hats to: several
(we ignore it).
- Remove code used for handling spoil events, as spoiling is not possible
anymore, because we keep consumers open for writing all the time.
MFC after: 4 days
After disscussing things I have decided to take the easy and
consistent 90% solution instead of aiming for the very involved 99%
solution.
If we allow forceful unmounts of DEVFS we need to decide how to handle
the devices which are in use through this filesystem at the time.
We cannot just readopt the open devices in the main /dev instance since
that would open us to security issues.
For the majority of the devices, this is relatively straightforward
as we can just pretend they got revoke(2)'ed.
Some devices get tricky: /dev/console and /dev/tty for instance
does a sort of recursive open of the real console device. Other devices
may be mmap'ed (kill the processes ?).
And then there are disk devices which are mounted.
The correct thing here would be to recursively unmount the filesystems
mounte from devices from our DEVFS instance (forcefully) and if
this succeeds, complete the forcefully unmount of DEVFS. But if
one of the forceful unmounts fail we cannot complete the forceful
unmount of DEVFS, but we are likely to already have severed a lot
of stuff in the process of trying.
Event attempting this would be a lot of code for a very far out
corner-case which most people would never see or get in touch with.
It's just not worth it.

big endian archs and fixes the compilation of libncp, netncp, etc. there.

o Move the sysctls under debug.psm.* and hw.psm.* making them a bit
clearer and more consistent with other drivers.
o Remove the debug.psm_soft_timeout sysctl. It was introduced many
moons ago in r1.64 but never referenced anywhere.
o Introduce hw.psm.tap_threshold and hw.psm.tap_timeout to control
the behaviour of taps on touchpads. People might like to fiddle
with these if tapping seems to slow or too fast for them.
o Add debug.psm.loglevel as a tunable so that verbosity can be set
easily at boot-time (to watch probes and such) without having to
compile a kernel with options PSM_DEBUG=N.
