The original commit was supposed to stop the ability to do raw frame
injection in monitor mode to arbitrary channels (whether supported
by regulatory or not) however it doesn't seem to have been followed
by any useful way of doing it.
Apparently AHDEMO is supposed to be that way, but it seems to require
too much fiddly things (disable scanning, set a garbage SSID, etc)
for it to actually be useful for spoofing things.
So for now let's just disable it and instead look to filter transmit
in the output path if the channel isn't allowed by regulatory.
That way monitor RX works fine but TX will be blocked.
I don't plan on MFC'ing this to -10 until the regulatory enforcement
bits are written.

The AR9380 and later chips have a 128KiB register window, so the register

The tools are about to be updated as well. No, they're not backwards

erroneously skip symbols that were not mangled at all. Fix this by
moving the return into the preceding if block.
While here, simplify the code by letting __cxa_demangle() allocate the
needed space for the demangled symbol. This also fixes a memory leak,
which would occur whenever __cxa_demangle() failed.

If powersave is enabled and there are any transitions to network
or full sleep - even if they're pretty damned brief - eventually
something messes up somewhere and the bus glue between the AR9331
SoC and the AR9331 wifi stops working. It shows up as stuck DMA
and LOCAL_TIMEOUT interrupts.
Both ath9k and the reference driver does a full chip reset if things
get stuck.
So:
* teach the AR9330 HAL about the force_full_reset option I added a
couple of years ago;
* if the chip is currently in full-sleep, do a full-reset;
* if TX DMA and/or RX DMA are still enabled (eg, they did get
stuck during reset) then do a full-reset.
Tested:
* AR9331 SoC, STA mode
pmap_enter(PMAP_ENTER_NOSLEEP). The PGA_WRITEABLE flag can be set
when either the page is busied, or the owner object is locked.
Update comments, move all assertions about page state when
PGA_WRITEABLE flag is set, into new helper
vm_page_assert_pga_writeable().

cheating by assigning the same sector offset to both directories,
but it seems that VirtualBox doesn't like that. Neither does
qemu from the looks of it. We now actually write the directory

Fix PR#20520 - predicate called too many times in list::remove_if.
Add tests for list, forward_list, and the std::remove_if algorithm
This fixes an issue where std::list<>::remove_if() and remove() could
erroneously visit elements twice.

While here, change how we check if the current line is the last one.
Before, we just checked if there were more files after the current one.
Now, we check the actual content of those files: they files may not have
a line at all. This matches the definition of the "last line" by the
Open Group.
The new behavior is closer to GNU sed.

mapping size (currently unused). The flags includes the fault access
bits, wired flag as PMAP_ENTER_WIRED, and a new flag
PMAP_ENTER_NOSLEEP to indicate that pmap should not sleep.
For powerpc aim both 32 and 64 bit, fix implementation to ensure that
the requested mapping is created when PMAP_ENTER_NOSLEEP is not
specified, in particular, wait for the available memory required to
proceed.

Correct the usage in both the manpage and in usage() to indicate
that the wait interval and repetition count may be given either
with the respective -w/-c arguments, or as the final positional
arguments. [0]
The corresponding code to implement the positional arguments has
been conditional on the (always-enabled) BACKWARD_COMPATIBILITY
macro since the original 4.4-lite import. It's no longer reasonable
to remove the functionality, so remove the macro and conditional
instead.
Note that multiple disks may be given on the command line.
While here, sort arguments and apply minor mdoc fixes.

nullfs vnode shares vnode lock with lower vnode, this allows the
reclamation of nullfs directory vnode in null_lookup(). In this
situation, VOP must return ENOENT.
More, since after the reclamation, the locks of nullfs directory vnode
and lower vnode are no longer shared, the relock of the ldvp does not
restore the correct locking state of dvp, and leaks ldvp lock.
Correct this by unlocking ldvp and locking dvp.
Use cached value of dvp->v_mount.

Add the ACPI MCFG table to advertise the extended config memory window.
Introduce a new flag MEM_F_IMMUTABLE for memory ranges that cannot be deleted
or moved in the guest's address space. The PCI extended config space is an
example of an immutable memory range.
Add emulation for the "movzw" instruction. This instruction is used by FreeBSD
to read a 16-bit extended config space register.
