db29be839a phabricator related changes:
- don't lint either contrib or crypto: these are both externally written
	  directories
	- add additional linters for spelling (check common typos like teh ->
	  the)
	- chmod linter checks for executible bit on bad files
	- merge-conflict checks for merge conflict tokens then may have been
	  resolved incorrectly
	- filename checks for back characters in filenames
	- json for json syntax correctness

	- remove history.immutable: it is meaningless on subversion, and causes
	  workflow problems when trying to use git.  It it set to 'true' by
	  default with hg

47a5593e1b Copy amd64/make-memstick.sh to arm64/make-memstick.sh for
aarch64 memory stick images.

Although arm64 does not yet have USB support, the memstick
image should be bootable with certain virtualization tools,
such as qemu.

c207ff9319 Always send log(9) messages to the message buffer.
It is truer to the semantics of logging for messages to *always*
go to the message buffer, where they can eventually be collected
and, in fact, be put into a log file.

This restores the behavior prior to r70239, which seems to have
changed it inadvertently.

4b8175ee8f When building VM disk images, vm_copy_base() uses tar(1) to
copy the userland from one md(4)-mounted filesystem to a clean
filesystem to prevent remnants of files that were added and
removed from resulting in an unclean filesystem.  When newfs(8)
creates the first filesystem with journaled soft-updates enabled,
the /.sujournal file in the new filesystem cannot be overwritten
by the /.sujournal in the original filesystem.

To avoid this particular error case, do not enable journaled
soft-updates when creating the md(4)-backed filesystems, and
instead use tunefs(8) to enable journaled soft-updates after
the new filesystem is populated in vm_copy_base().

While here, fix a long standing bug where the build environment
/boot files were used by mkimg(1) when creating the VM disk
images by using the files in .OBJDIR.

16028f6a5a vidcontrol: skip invalid video modes returned by vt(4)
vt(4) has a stub CONS_MODEINFO ioctl that does not provide any data
but returns success. This needs to be fixed in the kernel, but address
it in vidcontrol(1) as well in case it's run on an older kernel.

7144875388 Activate write-only optimization if bpf device opened with O_WRONLY.
dhclient opens bpf as write-only to send packets. It never reads received
packets from that descriptor, but processing them in kernel takes time.
Especially much time takes packet timestamping on systems with expensive
timecounter, such as bhyve guest, where network speed dropped in half.

62def911bd Refine the workaround for Intel HSD131 [1] added in r269052:
- Use the full mask described by the erratum as with a sufficiently high
  number of these false-positives, the overflow bit (bit 62) additionally
  gets set [7].
- HSD131 has been brought into several other Haswell-derived CPUs including
  to the next generation, i. e. Intel Broadwell. Thus, also skip reporting of
  these benign errors by default on CPU models affected by HSM142, HSW131 and
  BDM48 [2 - 5], describing the HSD131 silicon bug for additional models.
  Also, Celeron 2955U with a CPU ID of 0x45 have been reported to be covered
  by this fault [6], with the specification update concerned with HSM142 [2]
  only referring to 0x3c and 0x46.

5d18c60a93 Refactor out the _PXM -> VM domain lookup done in ACPI, in preparation for
its use in upcoming code.

This is inspired by something in jhb's NUMA IRQ allocation patchset.

However, the tricky bit here is that the PXM lookup for a node may
fail, requiring a lookup on the parent node.  So if it doesn't
exist, don't fail - just go up to the parent.  Only error out of the
lookup is the ACPI lookup returns an error.

56717743f2 Update pkt-gen to optionally use randomised source/destination
IPv4 addresses/ports.

When doing traffic testing of actual code that /does/ things to the
packet (rather than say, 'bridge.c'), it's typically a good idea to
use a variety of cache-busting and flow-tracking-busting packet
spreads.  The pkt-gen method of testing an IP range was to walk
it linearly - which is fine, but not useful enough.

This can be used to completely randomize the source/destination
addresses (eg to test out flow-tracking-busting) and to keep the
destination fixed whilst randomising the source (eg to test out
what a DDoS may look like.)

Tested:

* Intel ixgbe 10G (82599) netmap
