ufs_lookup.c:1.78. This is not currently a hazard, but the
bug would be activated by marking reiserfs as MPSAFE.

(The macro ultimately translates to KfRaiseIrql() which does use
the latter API, so this has no effect on generated code.)
Also, wait for thread termination the right way: kthread_exit()
will ultimately do a wakeup(td->td_proc). This is the event we
should wait on. Eliminate the previous synchronization machinery
for this since it was never guaranteed to work correctly.

version has a bug where it fails to properly cancel the polling loop
that periodically queries the BSSID (this is done to detect the
association/disassociation state). The timeout is supposed to fire
once a second, but the eloop_cancel_timeout() call uses a different
'user data' value than what was passed to eloop_register_timeout(),
so cancelling the timeouts fails. This results in an additional timeout
being created each time an EAPOL packet is received, which can lead
to dozens of unwanted timeouts firing every second instead of just one.

packets until zero interrupt cause register is

- If RX overrun comes in log this fact. [ NetBSD also
resets adapter in this case, but my tests showed that
this is not needed and only pessimizes behavior under
heavy load. ]
- Since almost all functions is rewritten, style the
remaining lines.
This fixes em(4) interfaces wedging under high load.

to unload the usb.ko module after boot if it was originally preloaded
from "/boot/loader.conf". When processing preloaded modules, the
linker erroneously added self-dependencies the each module's reference
count. That prevented usb.ko's reference count from ever going to 0,
so it could not be unloaded.
