When job control is not enabled, the shell ignores SIGINT while waiting for
a foreground process unless that process exits on SIGINT. In this case, the
foreground process is sleep and it does not exit on SIGINT because the
signal is only sent to the shell. Depending on order of events, this could
cause the SIGINT to be unexpectedly ignored.
On lightly loaded bare metal, the chance of this happening tends to be less
than 0.01% but with higher loads and/or virtualization it becomes more
likely.
Starting the sleep in background and using the wait builtin ensures SIGINT
will not be ignored.

This flag will now show the processor number on which a process is running.
This change was inspired by PR129965. Initially I didn't think that the
patch attached to it was correct -- it sacrificed ki_estcpu use in "cpu"
for ki_lastcpu and I thought that the old functionality should be kept and
the new (cpu#) one added to it. But I've since discovered that ki_estcpu is
sched_4bsd-specific. What's worse, it represents the same thing as
ki_pctcpu, except ki_pctcpu is universal -- so "%cpu" has been using it
successfully. Therefore, I've decided to replace information based on
ki_estcpu with information based on ki_oncpu/ki_lastcpu.
Key parts of the code and manual changes were borrowed from top(1).

These implementations of the bc and dc programs offer a number of advantages
compared to the current implementations in the FreeBSD base system:
- They do not depend on external large number functions (i.e. no dependency
on OpenSSL or any other large number library)
- They implements all features found in GNU bc/dc (with the exception of
the forking of sub-processes, which the author of this version considers
as a security issue).
- They are significantly faster than the current code in base (more than
2 orders of magnitude in some of my tests, e.g. for 12345^100000).
- They should be fully compatible with all features and the behavior of the
current implementations in FreeBSD (not formally verified).
- They support POSIX message catalogs and come with localized messages in
Chinese, Dutch, English, French, German, Japanese, Polish, Portugueze,
and Russian.
- They offer very detailed man-pages that provide far more information than
the current ones.
The upstream sources contain a large number of tests, which are not
imported with this commit. They could be integrated into our test
framework at a latter time.
Installation of this version is controlled by the option "MK_GH_BC=yes".
This option will be set to yes by default in 13-CURRENT, but will be off
by default in 12-STABLE.

-d and -v are not equivalent options. The former is more verbose than the
latter and the former does not actually send the signals while the latter does.
Let them have their own paragraphs.
From the point of view of the output, -v is equivalent to -s, so describe them
close to each other. The difference is that former actually sends the signals
and the latter doesn't.

This is a flag from the MAC that says the received packet didn't match
a keycache slot. This isn't technically a problem as WEP keys don't
match keycache slots (they're "global" keys), but it could be useful
for tracking down CCMP decryption failures.
Right now it's a no-op - it mirrors what the AR9300 HAL does and it
just increments a counter. But, hey, maybe one day I'll use it for
diagnosing keycache/CCMP decrypt issues.
but in System III in the AT&T world.
Examination of the TUHS archives shows this was present in 4.3-Reno

The only thing this tunable enables now is reporting to ACPI _OSC that
Active State Power Management and Clock Power Management Capability are
"supported" by the OS.
I've found that at least some Supermicro server boards do not allow OS
to support native PCIe hot-plug unless it reports those capabilities.
After spending significant time in PCIe specs I have found very little
motivation for that, and none of it applies to those motherboards, not
enabling ASPM themselves. So unless OS explicitly wants to save power,
I see nothing for it to do there actually.
I guess it may get sense to support ASPM when we get Thunderbolt support.
Otherwise I have no system with PCIe hot-plug where power saving matters.
It would be nice to enable this by default, but I worry that it affect
power saving of some laptops, even though I haven't noticed that myself.

If the interfaces on which wpa_supplicant is to run are not known or do
not exist, wpa_supplicant can match an interface when it arrives. Each
matched interface is separated with -M argument and the -i argument now
allows for pattern matching.
As an example, the following command would start wpa_supplicant for a
specific wired interface called lan0, any interface starting with wlan
and lastly any other interface. Each match has its own configuration
file, and for the wired interface a specific driver has also been given.

Not all interrupt sources that affect CIS bit were acknowledged.
Specifically, bits in STATESTS (aka WAKESTS) were left set.
The fix is to disable WAKEEN and clear STATESTS bits before the HDA
interrupt is enabled. This way we should never get any STATESTS bits.
I also added placeholders for all event bits that we currently do not
enable, do not handle and do not clear. This might get useful when / if
we enable any of them.
