- implement baseic stubs for capget, capset, prctl PR_GET_KEEPCAPS
and prctl PR_SET_KEEPCAPS.
- add SCM_CREDS support to sendmsg and recvmsg
- modify sendmsg to ignore control messages if not using UNIX
domain sockets
This should allow linux pulse audio daemon and client work on FreeBSD
and interoperate with native counter-parts modulo the differences in
pulseaudio versions.

Adventourous souls with an AR9220/AR9280 or later and who have a device
that sends PS-POLL frames may wish to try tinkering with this option and
get back to me.
Linux ath9k only enables this for AR9280 and later NICs; so
create a capability for it so it isn't enabled for earlier
NICs.
Enabling hardware PS-POLL support will come in a later commit
and will be disabled by default.
Since signal trampolines are copied to the shared page do not need to
leave place on the stack for it. Forgotten in the previous commit.

Even though they map to setting the error filter register,
ath9k also writes them untouched to AR_RX_FILTER.
The Force-BSSID match bit can stay high, as it maps to a
misc mode register setting rather than an RX filter bit.
The phyerr, radar and bssid-match bits aren't real bits, they map
to enabling bits in other registers. Move those out of the way of
valid RX filter bits.
Add a few new fields from ath9k - compba, ps-poll, mcast-bcast-all.

ath_hal needs a lot more work to encompass the list of supported
cards, as the AR5416/AR9160/AR9280/AR9285 list is quite long
and extensive. In addition, there's a lot of AR5212/AR5213 based
cards that aren't on this list.
CPUs. These CPUs need explicit MSR configuration to expose ceratin CPU
capabilities (e.g., CMPXCHG8B) to work around compatibility issues with
ancient software. Unfortunately, Rise mP6 does not set the CX8 bit in CPUID
and there is no MSR to expose the feature although all mP6 processors are
capable of CMPXCHG8B according to datasheets I found from the Net. Clean up
and simplify VIA PadLock detection while I am in the neighborhood.

Changes since 7.8.0 (from the official changelog):
- Fixed sporadic interrupt generation for associated CQ when processing
a local invalidate work request
- Changes to core scheduling to avoid starving requests from the host
under heavy RDMA Read Request load (e.g. packets to the wire)
- Programmed the tp tx resource limiter in function of the traffic (only
affects iWarp)
- Increased the egress NIC gather list length from 36 to 46 entries

Before it could change later and we were sending invalid mapsize.
Some time ago I added optimization where when nodes are connected for the
first time and there were no writes to them yet, there is no initial full
synchronization. This bug prevented it from working.

The second close(2) call resulted in heisenbugs in some multi-threaded
applications where e.g. dlopen(3) call in one thread could close a file
descriptor for a file having been opened in other thread concurrently.
My litmus test for this issue was an openoffice.org build.

If supplied length is zero, and user address is invalid, function
might return -1, due to the truncation and rounding of the address.
The callers interpret the situation as EFAULT. Instead of handling
the zero length in caller, filter it in vm_fault_quick_hold_pages().

Code inspection shows freebsd32_ioctl calls fget for a fd and calls
a subroutine to handle each specific ioctl. It is expected that the
subroutine will call fdrop when done. However many of the subroutines
will exit out early if copyin encounters an error resulting in fdrop
never being called.

the channel width is ni->ni_chw, which is set to the negotiated channel
width. ni->ni_htflags is the capability, rather than the negotiated

Teach both the TX path and the sample rate module about this.
This seems to work fine for STA but not HT/20 AP mode.
Further discussion with net80211 people will need to take place
to ensure that the right flags are set based on the negotiated
capabilities of the remote peer, rather than whatever the local
parameters are.
Sending short-gi frames in 20mhz may work on some chips but
it certainly isn't supported on anything currently supported
by the HAL; and sending HT40 frames in HT20 mode just plain
won't work.
settings, it seems that our defines are backwards and don't match what
is in the EEPROM documentation or internal driver.
The ath9k code used to have a bitfield here, rather than a uint8_t, and
there were #defines used to swap the order based on the endian of the
platform - this wasn't because of nybble or bit ordering of the
underlying host but because of what the compiler was doing.
This may be the reason for the backwards field numbers, as ath9k had
similar issues.

Ath9k sources indiciate that one of the ANI modes interferes with
RIFS detection, so match ath9k and disable that.
* The existing interrupt mitigation code didn't mitigate anything - the
per-packet TX/RX interrupts are still occuring. It's possible this
worked for the AR5416 but not any later chipsets; I'll investigate and
update as needed.
* Set both the RX and TX threshold registers whilst I'm at it.
This is verified to work on the AR9220 and AR9160. I'm leaving it off
by default in case it's truely broken, but I need to have it enabled

Add new RAID GEOM class, that is going to replace ataraid(4) in supporting
various BIOS-based software RAIDs. Unlike ataraid(4) this implementation
does not depend on legacy ata(4) subsystem and can be used with any disk
drivers, including new CAM-based ones (ahci(4), siis(4), mvs(4), ata(4)
with `options ATA_CAM`). To make code more readable and extensible, this
implementation follows modular design, including core part and two sets
of modules, implementing support for different metadata formats and RAID
levels.
Support for such popular metadata formats is now implemented:
Intel, JMicron, NVIDIA, Promise (also used by AMD/ATI) and SiliconImage.
Such RAID levels are now supported:
RAID0, RAID1, RAID1E, RAID10, SINGLE, CONCAT.
For any all of these RAID levels and metadata formats this class supports
full cycle of volume operations: reading, writing, creation, deletion,
disk removal and insertion, rebuilding, dirty shutdown detection
and resynchronization, bad sector recovery, faulty disks tracking,
hot-spare disks. For Intel and Promise formats there is support multiple
volumes per disk set.

Introduce new type of BIO_GETATTR -- GEOM::setstate, used to inform lower
GEOM about state of it's providers from the point of upper layers.
Make geom_disk use led(4) subsystem to illuminate states in such fashion:
FAILED - "1" (on), REBUILD - "f5" (slow blink), RESYNC - "f1" (fast blink),
ACTIVE - "0" (off).
LED name should be set for each disk via kern.geom.disk.%s.led sysctl.
Later disk API could be extended to allow disk driver to report this info
in custom way via it's own facilities.
Make `geom XXX list` and `geom XXX status` outputs more consistent:
Add -a options to print all geoms, not only ones with providers.
Add -g option for `status` to report geom's names, not provider's.
Make `status` by default report provider's status (if present), not geom's.
Make `status` report consumer's statuses, not only "synchronized" field.
