A number of tftp clients, including the one in Intel's pxe boot loader,
may intentionally stop a transfer using error code 0 (i.e., EUNDEF).
These are not real errors. Avoid spamming log files with these by
logging them at level LOG_DEBUG instead.
Discussed on -hackers with an initial patch proposal; this change is an
improved approach suggested by kan@.
Add the sysctl debug.iosize_max_clamp, enabled by default. Setting the
sysctl to zero allows to perform the SSIZE_MAX-sized i/o requests from
the usermode.

created with "gpart add -t ebr ...".
This should keep EBR partitions accessible after r231754 for those,
who have EBR on the partition with type 0x0f.

- In case the parent is bge(4), don't set the Jumbo frame settings unless
the MAC actually is Jumbo capable as otherwise the PHY might not have the
corresponding registers implemented. This is also in line with what the
Linux tg3 driver does.

process. Normally it will cause the child to exit followed by the
termination of the supervisor after removing the pidfile.
This looks like desirable behavior, because termination of a
supervisor usually supposes termination of its charge. Also it will
fix the issue with stale pid files after reboot due to init kills a
supervisor before its child exits.

not to leak the descriptor after exec(3). This raises the issue for
daemon(3) of the pidfile lock to be lost when the child process
executes.
To solve this and also to have the pidfile cleaned up when the program
exits, if a pidfile is specified, spawn a child to exec the command
and wait in the parent keeping the pidfile locked until the child
process exits and remove the file.

hold the lock.
This is part of my series of work to try and capture when net80211
locking isn't.
ObNote: it'd be nice to be able to mark a lock as "assert if the lock
is dropped", so I could capture functions which decide that dropping
and reacquiring the lock is a good idea (without re-checking the
sanity of the state protected by the lock.)
Without this change, pressing ^T could result in rc.d script putting

Vnode-backed mappings cannot be put into the kernel map, since it is a
system map.
Use exec_map for transient mappings, and remove the mappings with
kmem_free_wakeup() to notify the waiters on available map space.
Do not map the whole executable into KVA at all to copy it out into
usermode. Directly use vn_rdwr() for the case of not page aligned
binary.
There is one place left where the potentially unbounded amount of data
is mapped into exec_map, namely, in the COFF image activator
enumeration of the needed shared libraries.

This allows all of the athstats statistics to work again.
Specifics:
* The previous code used chars < 0x80 as printable, and chars >= 0x80
as "statistics"
* .. which meant any statistic above 127 would wrap around to 0;
* .. so once I added the 802.11n TX/RX statistics to athstats, the tail
end of the statistics list weren't accessible.
This patch:
* adds a define which represents the magic character, rather than a hard
coded one
* the statistic in question is little endian encoded after the magic
character.
Notes:
* statfoo is useful enough to possibly warrant turning into a library API.

At 16 FIBs a total of over 64k return codes/replies/stati are checked,
sometimes multiple times (in different ways, e.g. the reflected request
as well as ipfw counter values).
The scripts need two or three machines to run and are thus not added
