supports the Security Extensions or not. This bit is not the same as the CPU one.
Currently we are not checking for either before trying to write to the special
registers. This can lead to problems on hardware or simulators that do not
provide the security extensions. Add the missing checks. Their interactions with
the CPU flag is not entirely clear to me but using a macro will make it easier
to quickly adjust the condition once the CPU bits are sorted as well.

intention of the POSIX IEEE Std 1003.1TM-2008/Cor 1-2013.
A robust mutex is guaranteed to be cleared by the system upon either
thread or process owner termination while the mutex is held. The next
mutex locker is then notified about inconsistent mutex state and can
execute (or abandon) corrective actions.
The patch mostly consists of small changes here and there, adding
neccessary checks for the inconsistent and abandoned conditions into
existing paths. Additionally, the thread exit handler was extended to
iterate over the userspace-maintained list of owned robust mutexes,
unlocking and marking as terminated each of them.
The list of owned robust mutexes cannot be maintained atomically
synchronous with the mutex lock state (it is possible in kernel, but
is too expensive). Instead, for the duration of lock or unlock
operation, the current mutex is remembered in a special slot that is
also checked by the kernel at thread termination.
Kernel must be aware about the per-thread location of the heads of
robust mutex lists and the current active mutex slot. When a thread
touches a robust mutex for the first time, a new umtx op syscall is
issued which informs about location of lists heads.
The umtx sleep queues for PP and PI mutexes are split between
non-robust and robust.
Somewhat unrelated changes in the patch:
1. Style.
2. The fix for proper tdfind() call use in umtxq_sleep_pi() for shared
pi mutexes.
3. Removal of the userspace struct pthread_mutex m_owner field.
4. The sysctl kern.ipc.umtx_vnode_persistent is added, which controls
the lifetime of the shared mutex associated with a vnode' page.

FreeBSD zfs_ioc_rename() has an option, not present upstream, that
allows to rename snapshots without unmounting them first. I am not sure
what is a rationale for that option, but its actual behavior was the
opposite of the intended behavior. That is, by default the snapshots
were not unmounted.
The option was introduced as part of a large update from upstream in
r248498.
One of the consequences was a havoc under .zfs/snapshot after the rename.
The snapshots got new names but were mounted on top of directories with
old names, so readdir would list the new names, but lookup would still
find the old mounts.

objects with the same name in different sets.
Add optional manage_sets() callback to objects rewriting framework.
It is intended to implement handler for moving and swapping named
object's sets. Add ipfw_obj_manage_sets() function that implements
generic sets handler. Use new callback to implement sets support for
lookup tables.
External actions objects are global and they don't support sets.
Modify eaction_findbyname() to reflect this.
ipfw(8) now may fail to move rules or sets, because some named objects
in target set may have conflicting names.
Note that ipfw_obj_ntlv type was changed, but since lookup tables
actually didn't support sets, this change is harmless.

* The default kernel and options won't build the GPL PHY bits;
* bwn(4) defaults to building as a module anyway!;
* If BWN_GPL_PHY is specified in the config file, and you uncomment
the GPL PHY bits in the module Makefile, you'll get a working
N-PHY.
This is specifically designed to be obtuse for now, as I don't want
to flip it on by default. It's easy enough for people to flip on
and build, and it's a module so the default GENERIC kernel won't be
GPL tainted.
I'll have to add an actual HAL layer that allows the GPL PHY to be loaded
before if_bwn so it can be "magic", but that'll come later.

This is a GPLv2 PHY-N implementation based on the Linux b43 driver,

I've tested this on the BCM4321 11abgn device, in 11bg and 11a modes.
The b43 PHY code only supports 11abg, no 11n, and 20MHz only wide
channels.
Yes, this is a GPLv2 driver, so it won't be included in the
default builds.

PCIe PHY needs different initialization on MT7628/MT7688 SoCs than it does
on MT7620.
However, LEDE (and OpenWRT) dts files have the PCIe node for MT7628/MT7688
as compatible with mt7620-pci.
We already can handle this properly in our driver, so we just need to add
compat strings to fbsd-mt7628an.dtsi and the PCIe driver.

This is an import of the reworked LEDE dts files. Besides other things
they make it easier for us to reuse.
The only diffs left are for the following SoCs:
MT7620A (fbsd-mt7620a.dtsi)
MT7621 (fbsd-mt7621.dtsi)
MT7628 (fbsd-mt7628an.dtsi)
RT3883 (fbsd-rt3883.dtsi)
So we include the fbsd-*.dtsi files at the end of the original LEDE dtsi
files, using '#include "fbsd-xxxx.dtsi"'.
For example, for MT7621, the LEDE dtsi file is mt7621.dtsi. At the end of
it we add:
#include "fbsd-mt7621.dtsi"

This fixes booting on upcoming Intel systems with Kaby Lake processors.
