- Add few checks for group/pairwise ciphers into
ieee80211_parse_{wpa,rsn}().
- Split error code and cipher value in wpa_cipher() / rsn_cipher(); current
hack with (1 << 32) does not work - it's 1, not 0 (detected by CSA).
- Return IEEE80211_REASON_UNSUPP_RSN_IE_VERSION instead of
IEEE80211_REASON_IE_INVALID when version field is not equal to RSN_VERSION.
Tested with wpi(4) / urtwn(4) (HOSTAP mode).

We have 6 opcode rewriters for table opcodes. When `set swap' command
invoked, it is called for each rewriter, so at the end we get the same
result, because opcode rewriter uses ETLV type to match opcode. And all
tables opcodes have the same ETLV type. To solve this problem, use
separate sets handler for one opcode rewriter. Use it to handle TEST_ALL,
SWAP_ALL and MOVE_ALL commands.

In case if there is already running interface, a second non-sta
interface will omit scanning, going directly to RUN state. Handle
this case for adhoc mode appropriately.
Tested with RTL8821AU, 2 vaps in IBSS mode.
In particular, reset the DF_QUIET flag when detaching from a device so
that a driver that marks a device quiet doesn't dictate policy for a
different driver that may claim the device in the future.

- Certain pic_assign_cpu, e.g. msi_assign_cpu can have quite a long
call chain. For msi_assign_cpu, mutex makes complex PCI bridge
drivers more tricky, e.g. sleep can note be called, etc, it will
be pretty tricky for upcoming Hyper-V PCI bridge driver for PCI
pass-through.
- It is not used on any hot code path nor non-sleepable context, so
sx should have the same effect as mutex.
PIC list is still protected by mutex to keep suspend/resume work.

* Don't do RTS/CTS - experiments show that we get ACK frames for each of them
and this ends up causing the timestamps to look all funny.
* Set the HAL_TXDESC_POS bit, so the AR9300 HAL sets up the hardware to return
location and CSI information.
- evdev_set_methods call is not required if actual methods are no-ops
- evdev_set_serial is also optional if there is no meaningful input device
identifier
- evdev_set_id on the other hand is mandatory, so set virtual bus with
dummy vendor/product/version

Add generic evdev support to touchscreen part of ti_adc: two absolute
coordinates + button touch to indicate pen position. Pressure value
reporting is not implemented yet.

evdev is a generic input event interface compatible with Linux
evdev API at ioctl level. It allows using unmodified (apart from
header name) input evdev drivers in Xorg, Wayland, Qt.
This commit has only generic kernel API. evdev support for individual
hardware drivers like ukbd, ums, atkbd, etc. will be committed later.
Project was started by Jakub Klama as part of GSoC 2014. Jakub's
evdev implementation was later used as a base, updated and finished
by Vladimir Kondratiev.

The flag specifies that the block which uses FPU must be executed in
critical section, i.e. take no context switches, and does not need an
FPU save area during the execution.
It is intended to be applied around fast and short code pathes where
save area allocation is impossible or undesirable, due to context or
due to the relative cost of calculation vs. allocation.

Move PMAP_TS_REFERENCED_MAX out of the various pmap implementations and
into vm/pmap.h, and describe what its purpose is. Eliminate the archaic
"XXX" comment about its value. I don't believe that its exact value, e.g.,
5 versus 6, matters.
Update the arm64 and riscv pmap implementations of pmap_ts_referenced()
to opportunistically update the page's dirty field.
On amd64, use the PDE value already cached in a local variable rather than
dereferencing a pointer again and again.

An array of bucket locks is added.
All modifications still require the global cache_lock to be held for
writing. However, most readers only need the relevant bucket lock and in
effect can run concurrently to the writer as long as they use a
different lock. See the added comment for more details.
This is an intermediate step towards removal of the global lock.

Our shim for Solaris random_get_bytes() uses read_random(), that looks
reasonable, since it guaranties reliably seeded random data. On the other
side Solaris random_get_pseudo_bytes() does not provide this guarantie,
and its original Solaris implementation is equivalent to our arc4rand(),
using software crypto without stressing slower hardware RNG.
