On platforms which are fully IO-coherent, the map might be null.
We need to guarantee that all data is observable after the
sync operation is called. Add a memory barrier to ensure that on ARM.

to be negotiated, it could be a Kerberized mount. As such, filling
in the "principal" argument using the canonized host name makes sense.
If it is negotiated as AUTH_SYS, the "principal" argument is meaningless
but harmless.

The number of available lock list entries for a thread is LOCK_CHILDCOUNT,
and each entry can record up to LOCK_NCHILDREN locks. When iterating over
the locks held by a thread, a bound on the loop index is therefore given
by LOCK_CHILDCOUNT * LOCK_NCHILDREN; WITNESS_COUNT is an unrelated
constant.

The UEFI loader on the 10.1 release install disk (disc1) modifies an
existing EFI_DEVICE_PATH_PROTOCOL instance in an apparent attempt to
truncate the device path. In doing so it creates an invalid device
path.
Perform the equivalent action without modification of structures
allocated by firmware.

Place sched_random nearer to where it's first used: moving the
code nearer to where it is used makes the code easier to read
and we can reduce the initial "#ifdef SMP" island.
Reword a little the comment and clean some whitespaces
while here.
The 6205 (Taylor Peak) in the Lenovo X230 works fine in 5GHz 11a and 11n HT20,
but not 11n HT40. The NIC goes RX deaf the moment HT40 is configured.
It's so RX deaf that it doesn't even hear beacons and the firmware sends
"BEACON MISS" events. That's pretty deaf.
I tried configuring up the HT40 flags in monitor mode and it worked - so
I assumed that doing the transition from 20 -> 40MHz channel configuration
when going auth->assoc (ie, after the NIC has been partially configured)
is a problem.
So for now, let's just always set them if they're available.
Tested:
* Intel 5300, STA mode, 5GHz HT/40 AP; 2GHz HT/20 AP
* Intel 6205, STA mode, 5GHz HT/40, HT20, 11a AP; 2GHz HT/20 AP
This was pointed out to me by coworkers trying to use FreeBSD-HEAD
in the office on their Thinkpad T420p laptops.
TODO:
* I don't like how the HT40 flags are configured - the whole interop/
protection config should be re-checked. Notably, I think curhtprotmode
is 0 in a lot of cases, which means "no interoperability" and i think
that's busted.

As always, this isn't license for wholesale change, etc.
Some external tools just do a 'ls /dev/vmm' to figure out the bhyve virtual
machines on the host. These tools break if the devmem device nodes also
appear in /dev/vmm.

The /etc/ttys entry for a serial console in FreeBSD/x86 is as follows:
ttyu0 "/usr/libexec/getty 3wire" vt100 onifconsole secure
The initial terminal type passed to getty(8) is "3wire" which sets the
CLOCAL flag. However reset(1) clears this flag and any programs that try
to open the terminal will hang waiting for DCD to be asserted.
Fix this by always asserting DCD and DSR in the emulated uart.

pointer is NULL, as in that case there are no userland pages that
could potentially be wired. It is common for old to be NULL and
oldlenp to be non-NULL in calls to userland_sysctl(), as this is used
to probe for the length of a variable-length sysctl entry before
retrieving a value. Note that it is typical for such calls to be made
with an uninitialized value in *oldlenp, so sysctlmemlock was
essentially being acquired at random (depending on the uninitialized
value in *oldlenp being > PAGE_SIZE or not) for these calls prior to
this patch.
