I changed. That is never a good sign.
1) only map 1 page at address zero, not 4096 pages
2) page 1 starts at address 4096 (PAGE_SIZE) not 4095 (PAGE_MASK). I
don't even want to think what the pte's looked like.
3) subtract the r/o page group start address from the end before
converting it to a count. Otherwise an extra page is mapped.
If you were affected by this, the symptoms of this was a hang at boot
after the spinner. Sorry folks. :-(

accesses softc after it is freed. Use a different malloc type for
softc than the rest of the bus code to make it more clear when these
things happen that it is the driver that's at fault, not the bus code.

timeout would continue to happen: boom! Fix this[*] by timing out earlier.
[*] almost fixes the race on unload: wi_inquire could be running when
untimeout is called, and there's no way to know when it has actually
returned. This race is very rare and hard to lose.

* Test /etc/motd for writability before trying to update it. This is
especially useful when /etc/ is mounted ro, like on a diskless boot.
(Thanks to phk for the idea on this one.)
* Make the "updating" message reflect what actually happens.
character 1 byte past the end of cmdline[] when libedit is being used for
input, and avoid writing a null pointer 1 element past the end of margv[].

o don't grab the mutex at the top of ath_detach; it does nothing
useful
o deal with entry to ath_ioctl during detach to disable promiscuous

the device is marked invalid as the code isn't prepared to deal
with it (in particular by that time the hal reference may have

use because a kernel thread is borrowing it. The borrowed page table
can change spontaneously, making any dependence on its continued use
subject to a race condition.
- _pmap_unwire_pte_hold() cannot use pmap_is_current(): If a change is
made to a page table page mapping for a borrowed page table, the TLB
must be updated.

you on the current queue. In the future, it would be nice if priority
propagation could deterministicly pluck a thread off of the next queue
and put it on the current queue. Until then this hack stops us from
holding up our entire current queue, including interrupt handlers, while
a thread on the next queue is blocked while holding Giant.
