Morse code standards to the bcd(6) manpage (which also serves as the
manpages ppt(6) and morse(6)).
(The only one of these standards I have read is the ECMA-10 paper tape
standard, which is also probably the least readily available, since
ECMA don't supply copies of obsolete standards, though they will
supply printed copies of any or all of their current standards at no
charge.)

too. Remove some needless code duplication by adding a "drain" argument
to the ACQUIRE() macro (compiler can [and does] optimize the constant
conditional).
free a PV page if the PV entry was associated with the kernel pmap,
since the kernel pmap is locked, and freeing the page will execute
a code path which will attempt to lock it again, resulting in deadlock.
No real loss, since the next time a PV entry is freed, the page will
be freed, too.
unsigned char rather than char for values that end up passed to
isascii() and also used as array indices.

with variations in EINTR behaviour, but the optimisation of using the
BSD version where the SYSV version isn't needed is insignificant.
This patch therefore simplifies the code by making there be just one
version, a more paranoid (about EOF when errno is already EINTR)
version of the SYSV code. Since the BSD/SYSV defines are mainly used
to control whether BSD timers are used, this helps where BSD timers
but SYSV EINTR handling are wanted.

- fix command name in SYNOPSIS section of man page.
- link ktrace man page to ktruss man page.
- add executable and man page for ktruss in distrib sets.
allowing the user to choose the name of the save file and specify it
on the command line when restoring. It also eliminates a buffer
overrun in determining the path to the save file, and any particular
arbitrary limit on the name length. In the name of a tidier home
directory, the default name is changed from "Bstar" to ".Bstar".

Minor modification (s/startup/filename/ in initialize()) by me.
locking primitive directly to lock it, since those will never attempt
to call printf() to display debugging information (and thus deadlock
on recursion into the kprintf_slock).
- Now compatible with MULTIPROCESSOR (requires other changes not yet
committed, but which will be later today).
- In addition to tracking simple locks, track exclusive spin locks.
- Count spin locks like we do sleep locks (in the cpu_info for this
CPU).
- Lock debug lists are now TAILQs, so as to make the locking order
more obvious when dumping the list.
Also, some suggestions from Bill Sommerfeld:
- SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED constants, which may be
defined in <machine/lock.h> (default to 1 and 0, respectively). This
makes it easier to support architectures which use test-and-clear
rather than test-and-set.
- Add __attribute__((__aligned__)) to the `lock_data' member of the
simplelock structure. This makes it easier to support architectures
which can only perform atomic operations on very-well-aligned memory
locations. NOTE: This changes the size of struct simplelock, and
will cause a version bump.
once for ipv6. This patch makes the ipv6 case pass NULLs in for fast
and slow timeouts iff defined(INET) and passes in the right function
if !defined(INET).
