and want to have crypto support loaded as KLD. By moving zlib to separate
module and adding MODULE_DEPEND directives, it is possible to use such
configuration without complication. Otherwise, since IPSEC is linked with
zlib (just like crypto.ko) you'll get following error:
interface zlib.1 already present in the KLD 'kernel'!

Otherwise a kernel build would break in the coda5 module if the main
kernel conf file enabled CODA_COMPAT_5, too. Redefined symbols are
strictly disallowed by -Werror.
To overcome this issue, introduce a different symbol indicating coda5
build, CODA5_MODULE, and translate it to CODA_COMPAT_5 appropriately
in /sys/coda/coda.h.

doing it in aio_bio_done_notify.
3. In aio_bio_done_notify, don't send notification if KAIO_RUNDOWN

4. Use assignment to initialize aiothreadflags.
5. AIOCBLIST_RUNDOWN is not useful, axe the code using it.
6. use LIO_NOP instead of zero.

we no longer clear endpoint stalls every time a pipe is opened.
Previously we could assume an initial toggle value of zero because
the clear-stall operation resets the device's toggle state.

(atkbd(4)) and PS/2 mouse (psm(4)) are used together.
Turns out that atkbd(4) check_char() method may return "true" while
read_char() method returns NOKEY. When this happens kbdmux(4) was
simply stuck in the dead loop. Avoid dead loop in kbdmux(4) by breaking
out of the loop if read_char() method returns NOKEY.
It almost seems like a bug in atkkbd(4), atkbd_check_char() calls
kbdc_data_ready(), and, the later will return "true" if there are
pending data in either kbd or aux queue. However, because both aux
and kbd are on the same controller, I'm not sure if this is a bug
or feature.

Utilize the fact the module will support all frames by default --
it needs no ETHER_* options unless some frames need to be disabled.
Fix the comment respectively.
Don't forget to create fake opt_ef.h if no ETHER_* are set.

o Add defines for the 5 interrupt sources typical for serial devices.
These defines can be used for more finegrained interrupt handling
between drivers that cooperatively handle multiple serial ports.
o Add defines for the various bitmasks applicable when all information
is passed between drivers as a single integral.
Return BUS_PROBE_LOW_PRIORITY for a successful probe. This is in
preparation of the introduction of scc(4), which is going to handle
SCCs in the near future.

- Don't use callout_drain() to stop the toffhandle callout while holding the
fdc mutex (this could deadlock) in functions called from softclock
(callouts aren't allowed to do voluntary sleeps). Instead, use
callout_stop(). Note that since we hold the associated mutex and are now
using callout_init_mtx(), callout_stop() is just as effective as
callout_drain(). (Though callout_drain() is still needed in detach to
make sure softclock isn't contesting on our mutex before we destroy the
mutex.)
- Remove unused callout 'tohandle' from softc.
