The general idea is the same for all three files, though:
* Get rid of upstream build infrastructure (CMakeLists, Makefiles, etc)
* Delete tests, tools and utilities we don't want or use (including
samples)
* Remove various bits of upstream metadata files that we don't want or
use (.arcconfig, .gitignore, etc)
There's a bug in the ticks handling where when initialised at '0', once
the ticks counter wrapped the comparison math would never trigger.
The pps calculation would never happen, and thus aggregation was never
enabled.
It manifests itself as "oh you only get 11n transmit aggregation for the
first 10 minutes of uptime."
I'm sure there are other ticks related issues lurking in net80211.
Tested:
* ath / iwn, both with 'wlandebug +11n' and a little bit of iperf to
kick off the transmit A-MPDU negotiation once the pps gets high enough.

The magic number MSDOSFS_ARGSMAGIC, which used to distinguish
"old" vs "new" msdosfs mount arguments, has not been used since
2005; it should just go away now.
Likewise, the local-to-Unicode table that changed at the same
time is unused.
Leave the space reserved in the old style mount arguments, though,
since we still support the old mount call (via the cmount entry
point).

This is based on the AP135 design - QCA9558 SoC, 3x3 2GHz wifi, but no
5GHz (11n or 11ac) chip is available.
It however still has 128MiB of RAM, 16MiB of NOR flash and the AR8327N

This allows us to get rid of bzero which was added specifically to make
mtx_init on p_mtx reliable.
This also fixes a potential problem where mtx_init on other mutexes
could trip over on unitialized memory and fire an assertion.

proc_set_cred_init can be used to set first credentials of a new
process.
Update proc_set_cred assertions so that it only expects already used
processes.
This fixes panics where p_ucred of a new process happens to be non-NULL.

Prior to this change the kernel would take p1's credentials and assign
them tempororarily to p2. But p1 could change credentials at that time

named objects to zero before the virtual address is selected. Previously,
the color setting was delayed until after the virtual address was
selected. In rtld, this delay effectively prevented the mapping of a
shared library's code section using superpages. Now, for example, we see
the first 1 MB of libc's code on armv6 mapped by a superpage after we've
gotten through the initial cold misses that bring the first 1 MB of code
into memory. (With the page clustering that we perform on read faults,
this happens quickly.)

Fix this by increasing l2->l2_occupancy before we try to alloc (and decrease

- Use real locking, replace Giant with global sx protecting the
subsystem. Since the subsystem' lock is no longer dropped during
the sleepsk, remove not needed SHMSEG_WANTED segment flag, and
revert r278963.
- To do proper code simplification possible after the change of the
lock, restructure several functions into _locked body and
originally-named wrapper which calls into _locked variant. This
allows to eliminate the 'goto done2' spread over the code.
- Merge shm_find_segment_by_shmid() and shm_find_segment_by_shmidx().
- Consistently change all function prototypes to ANSI C.

appears to be too inaccurate that it can be used to synchronize the
playback data stream. If there is a recording endpoint associated with
the playback endpoint, use that instead. That means if the isochronous
OUT endpoint is asynchronus the USB audio driver will automatically
start recording, if possible, to get exact information about the
needed sample rate adjustments. In no recording endpoint is present,
no rate adaption will be done.
While at it fix an issue where the hardware buffer pointers don't get

These are actually almost the same units; except one is 3x3 5GHz, and
one is 2x2 5GHz.
Tested:
* TP-Link TL-WDR3600
TODO:
* The ath0/ath1 MAC addresses are ye garbage (00:02:03:04:05:06); fixing
that will take a little more time. It works fine with the ath0/ath1
MAC addresses set manually.
* Go through and yank the AR9344 on-board switch config (arswitch1);
it's not required here for this AP.
The AR934x (and maybe others in this family) have a more complicated
GPIO mux. The AR71xx just has a single function register for a handful
of "GPIO or X" options, however the AR934x allows for one of roughly
100 behaviours for each GPIO pin.
So, this adds a quick hints based mechanism to configure the output
functions, which is required for some of the more interesting board
configurations. Specifically, some use external LNAs to improve
RX, and without the MUX/output configured right, the 2GHz RX side
will be plain terrible.
It doesn't yet configure the "input" side yet; I'll add that if
it's required.
Tested:
* TP-Link TL-WDR3600, testing 2GHz STA/AP modes, checking some
basic RX sensitivity things (ie, "can I see the AP on the other
side of the apartment that intentionally has poor signal reception
from where I am right now.")
Whilst here, fix a silly bug in the maxpin routine; I was missing
a break.
Previously format string traversal could happen while the string itself was
being modified.
Use allproc_lock as coredumping is a rare operation and as such we don't
have to create a dedicated lock.

Currently we update timestamps unconditionally when doing read or
write operations. This may slow things down on hardware where
reading timestamps is expensive (e.g. HPET, because of the default
vfs.timestamp_precision setting is nanosecond now) with limited
benefit.
A new sysctl variable, vfs.devfs.dotimes is added, which can be
set to non-zero value when the old behavior is desirable.
