For the curious:
There's been many revisions to the Japan regulatory rules.
Apparently, the requirements require old cards certified on a previous
version of the rules to obey the older rules, not the newer rules.
The regdomain.xml outlines the -current- restrictions.
The card driver (eg the ath_hal regulatory domain code) may include
previous revisions of the Japan rules.
The ath_hal regdomain code populates the initial channel list based on
what the EEPROM indicates is possible. The regdomain.xml database imposes
further restrictions on this.
So regdomain.xml only needs to have the -current- rules. If the card
was certified on an earlier set of JP rules, it may only support a subset
of those channels - these are calculated at device attach and this
restricted list is kicked to net80211. regdomain.xml operates on -this-
list of channels.
And thus, the correct regulatory behaviour for Japan is handled with only
one regdomain.xml Japan database entry.

system timer is stopped during shutdown and that the pause() statement in ukbd
causes infinite hang in this regard. The fix is to use mi_switch() instead of
pause() to do the required task switch to ensure that the required USB processes
get executed.

r179247 introduced a possibility of devfs_allocv() returning spurious
ENOENT. If the vnode is selected by vnlru daemon for reclamation, then
devfs_allocv() can get ENOENT from vget() due to devfs_close() dropping
vnode lock around the call to cdevsw d_close method.
Use LK_RETRY in the vget() call, and do some part of the devfs_reclaim()
work in devfs_allocv(), clearing vp->v_data and de->de_vnode. Retry the
allocation of the vnode, now with de->de_vnode == NULL.
The check vp->v_data == NULL at the start of devfs_close() cannot be
affected by the change, since vnode lock must be held while VI_DOOMED
is set, and only dropped after the check.

cycle mode as timecounter just works fine. My best guess is that a firmware
update has fixed this, check at run-time whether it advances and use a
positive quality if it does. The latter will cause this timecounter to be
used instead of the tick counter based one, which just sucks for SMP.
- Remove a redundant NULL assignment from the timecounter initialization.
as STX_CTRL_PERF_CNT_CNT0_SHIFT actually is zero, if we were using the
second counter in the upper 32 bits this would be required though as the MI
timecounter code doesn't support 64-bit counters/counter registers.
- Remove a redundant NULL assignment from the timecounter initialization.
- Consistently use the newly introduced sc_mac_rxcfg throughout the driver
instead of reading the old content of CAS_MAC_RX_CONF.
- Increment if_iqdrops instead of if_ierrors in case of RX buffer allocation
failure.
- According to the Cassini datasheet the RX MAC should also be disabled in
cas_setladrf() before changing its configuration.
- Add error messages to gem_disable_{r,t}x() and take advantage of these
throughout the driver instead of duplicating their functionality all over
the place.
sets GEM_MAC_RX_CONFIG based on sc_mac_rxcfg which in turn is initialized
to zero, before reading the supposedly default configuration we were
effectively not basing sc_mac_rxcfg and thus GEM_MAC_RX_CONFIG on the
default configuration. Solve this by calling gem_setladrf() after reading
in the default configuration of GEM_MAC_RX_CONFIG. This also avoids the
need to distinguish whether gem_setladrf() should enable the RX MAC again
and should be slightly more correct as we're now doing all of the RX MAC
configuration in the intended step.
bogusly casts its contents around causing alignment faults on sparc64 and
most likely also on at least powerpc. Fix this by copying the contents
bytewise instead as partly already done here. Solving this the right way
costs some space, i.e. 148 bytes with GCC and 16 bytes with clang on x86
there are still some bytes left there though, and an acceptable hack which
tricks the compiler into only using a 2-byte alignment instead of the native
one when accessing the contents turned out to even take up more space that.
