crashes that had sn0 as the irq that's being serviced, when there was
no sn0 in the system. This seems to prevent them. Also, we want to
wait until after we've registered with the network layer before we
turn on the interrupt spigot to avoid races.
* Add MLINKS for:
-> Soundblaster emu10k1(4) Driver [points to pcm(4)]
-> Avance Logic ALS400 Driver [points to pcm(4)]
We should not need separate manual page for each of these
drivers; instead, linking them to pcm(4) manual page is
simpler, and new device lists can be easily added to the
said manual page.
* While I am here, sort out mdoc(7) entries in ${MAN}.
- redo updating.

- switch to use new low level rijndael api.
- stop using u8, u16 and u32.
- space cleanup.

do only unlink the file if we could indeed overwrite the file.
Old behaviour: rm -P /tmp/foo (foo mode 0444) would NOT overwrite foo,
but still delete it (with a warning: rm: foo: Permission denied)
New behaviour: Just the EPERM warning, but no deletion

free one sem_undo with un_cnt == 0 instead of all of them. This is a
temporary workaround until the SLIST_FOREACH_PREVPTR loop gets fixed so
that it doesn't cause cycles in semu_list when removing multiple adjacent
items. It might be easier to just use (doubly-linked) LISTs here instead
of complicated SLIST code to achieve O(1) removals.
This bug manifested itself as a complete lockup under heavy semaphore use
by multiple processes with the SEM_UNDO flag set.

Only update them in the newly created context to reflect the state
after copying the dirty registers onto the user stack. If we were to
update the trapframe, we lose the state at entry into the kernel. We
may need that after we create the context, such as for KSE upcalls.
We have to update the trapframe after writing the dirty registers to
the user stack for signal delivery to work. But this is best done in
sendsig() itself where it applies, not in get_mcontext() where it's
done unconditionally.
with debugger, so testing P_TRACED in SIGPENDING is useless. This test also
is the culprit which causes lots of 'failed to set signal flags properly for
ast()' to be printed on console which is just a false complaint.

- In order to avoid a race condition in multithreaded applications, the
check and removal operations by munmap(2) must be in the same critical
section. To accomodate this, vm_map_check_protection() is modified to
require its caller to obtain at least a read lock on the map.

Fix a done list handling bug which exhibits under high shared
interrupt rate and bus traffic. As the interrupt register is
read after checking hcca_done_head, there was a small chance
of dropping a done list. Ignore OHCI_WDH interrupt bit if
hcca_done_head is zero so that OHCI_WDH is processed later.

Update actlen even in the case where a TD returns an error --
this is critical for the umass bulk-only STALL case.

Ignore a CRCTO error on a SETUP transaction in combination with
STALLED or NAK. This fixes problems with the GL641.
- remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD().
this mirrors the functionality of SLIST_REMOVE_HEAD() (the other
singly-linked list type) and FreeBSD's STAILQ_REMOVE_HEAD()
ahc(4) sections.
Trim devices from sis(4), de(4), and ex(4).
Don't bother saying what standards are supported by the ATM stack;
this list is kind of misplaced here (and may not even be accurate
anymore).
Delete mention of pca; this driver has been removed.
