- Only check that EDD packet mode is available once at the start of
zfsldr rather than for each disk sector now that we read data in one
sector at a time. As a result, collapse the remaining bits of read
up into nread and rename nread to read.

Remove message about non empty bootcode, we can not break something
while GEOM_PART_EBR_COMPAT is defined.
But without GEOM_PART_EBR_COMPAT any changes in EBR are allowed and we
can accidentally wipe the boot code. To do not break anything save
the first EBR chunk and keep it untouched each time when we are
changing EBR. Note that we are still not support boot code for EBR.

machine checks (e.g. invalid PCI configuration cycles), but these can
be caught and recovered from. This change also the RTAS PCI driver to
work without modification as a replacement for the Grackle driver on
Grackle-based Powermacs.
The DFS code was tickling the channel set directly whilst going
through the state RUN -> CSA -> RUN. This only changed the channel;
it didn't go via ath_reset(). However in this driver, a channel
change always causes a chip reset, which resets the beacon timer
configuration and interrupt setup. This meant that data would go
out but as the beacon timers never fired, beacons would never
be queued.
The confusing part is that sometimes the state transition was
RUN -> SCAN -> CAC -> RUN (with CSA being in there sometimes);
going via SCAN would clear sc_beacons and thus the transition
to RUN would reprogram beacon transmission.
In case someone tries debugging why suspending a device currently
beaconing (versus just RX'ing beacons which is what occurs in STA
mode), add a silly comment which should hopefully land them at
this commit message. The call to ath_hal_reset() will be clearing
the beacon config and it may not be always reset.

This doesn't at all actually do radar detection! It's just
so developers who wish to test the net80211 DFS code can easily
do so. Without this flag, the DFS channels are never marked
DFS and thus the DFS stuff doesn't run.

It appears that the addition to uath(4) came in through PR kern/135009,
which had tested another device, the SMCWUSBTG2, successfully with uath(4)
and included the SMCWUSBG as it "has the same chipset". I can find no
other evidence that these two do actually share the same chipset. Moreover,
Linux treats the SMCWUSBG as a zyd(4) device also.

In cdregister(), hold the periph lock semaphore during changer
probe/configuration. This removes a window where an open of the
cd device may succeed before probe processing has completed.
In camisr_runqueue(), we need to run the sims queue regardless of
whether or not the current peripheral has more work to do. This
reverts a change mistakenly made in revision 223081.

Be anal and define the maximum period to be at least 4G seconds.

The knob was to work around CPU stopping issues, which since have been
either fixed or greatly reduced. kdb should really operate in a special

... and also increase the timeout.
It's better to try to proceed somehow despite stuck CPUs than to hang
indefinitely. Especially so during shutdown and when entering kdb or panic.
Timeout value is still an aribitrary value.
Timeout diagnostic is just a printf; the work on something more
debuggable is planned by attilio. Need to be careful here as
stop_cpus_hard is called very early while enetering kdb and soon(-ish)
it may become called very early when entering panic.
