This allows us to use it when we only need to check if the virtual address

The old vendor tree was never fully merged and doing partial merge isn't
supported with git subtree merge so a new one was created.
Switch the build to use the new DTS from sys/contrib/device-tree
This also bump the DTS used to be in sync with Linux 5.9
While here change the way to get the linux version, simply hardcode
the value in sys/dts/freebsd-compatible.dts and use awk to get that
to put it in the CFLAGS.
As a bonus we now have the bindings docs available
in sys/contrib/device-tree/Bindings/ so no need to link to the Linux repo
or to the vendor tree.
It changed the #pinctrl-cells value to be equal to 2 and the macro
that generates the values.
Based on the bindings docs a value of 2 is only acceptable if the node
used pinctrl-single,bits and not pinctrl-single,pins
This allow booting further on the beaglebone black with 5.9 DTS
A more complete fix for this function is being worked on in D28054. Fix
the uninitialized variable error so that builds can at least proceed.

When timestamp support has been negotiated, TCP segements received
without a timestamp should be discarded. However, there are broken
TCP implementations (for example, stacks used by Omniswitch 63xx and
64xx models), which send TCP segments without timestamps although
they negotiated timestamp support.
This patch adds a sysctl variable which tolerates such TCP segments
and allows to interoperate with broken stacks.

The purpose of this KASSERT is to ensure that we do not run out of space
in the early devmap. However, the devmap grew beyond its initial size of
2MB in r336519, and this assertion did not grow with it.
A devmap mapping of a 1080p framebuffer requires 1920x1080 bytes, or
1.977 MB, so it is just barely able to fit without triggering the
assertion, provided no other devices are mapped before it. With the
addition of `options GDB` in GENERIC by bbfa199cbc, the uart is now
mapped for the purposes of a debug port, before mapping the framebuffer.
The presence of both these conditions pushes the selected virtual
address just below the threshold, triggering the assertion.
To fix this, use the correct size of the devmap, defined by
PMAP_MAPDEV_EARLY_SIZE. Since this code is shared with RISC-V, define
it for that platform as well (although it is a different size).

In particular, using GELI on a root filesystem will only use
accelerated software crypto drivers if they are available before the
root filesystem is mounted. While these modules can be loaded from
the loader, including them in GENERIC provides a better out-of-the-box
experience for users.
Both aesni(4) and armv8crypto(4) provide accelerated implementations
of the default cipher used by GELI (AES-XTS) in addition to other
ciphers.

"snps,dw-wdt"-compatible watchdog device.
Tested on RK3399-based board (RockPro64).
Once started watchdog device cannot be stopped.
Interrupt handler has mode to kick watchdog even when software does not do it
properly.
This can be controlled via sysctl: dev.dwwdt.prevent_restart.
Also - driver handles system shutdown and prevents from restart when system
is asked to reboot.

Currently we create link-local route by creating an always-on IPv6 prefix
in the prefix list. This prefix is not tied to the link-local ifa.
This leads to the following problems:
First, when flushing interface addresses we skip on-link route, leaving
fe80::/64 prefix on the interface without any IPv6 addresses.
Second, when creating and removing link-local alias we lose fe80::/64 prefix
from the routing table.
Fix this by attaching link-local prefix to the ifa at the initial creation.
