b1b5cae2c8 Brad Davis identified a problem with the new LRO code, VLAN's
no longer worked. The problem was that the defines used the
same space as the VLAN id. This commit does three things.
1) Move the LRO used fields to the PH_per fields. This is
   safe since the entire PH_per is used for IP reassembly
   which LRO code will not hit.
2) Remove old unused pace fields that are not used in mbuf.h
3) The VLAN processing is not in the mbuf queueing code. Consequently
   if a VLAN submits to Rack or BBR we need to bypass the mbuf queueing
   for now until rack_bbr_common is updated to handle the VLAN properly.

9192bf1a16 amd64 pmap: implement per-superpage locks
The current 256-lock sized array is a problem in the following ways:
- it's way too small
- there are 2 locks per cacheline
- it is not NUMA-aware

Solve these issues by introducing per-superpage locks backed by pages
allocated from respective domains.

This significantly reduces contention e.g. during poudriere -j 104.
See the review for results.

b78b1e2544 Mark "private use area" characters as printable.
At least some of the characters in E000-F8FF range are used by Powerline
fonts, and having no attributes for these ranges in UnicodeData.txt
other than "Other, Private Use" it should be safe to mark all of them as
printable.  Some actually were before r340491, so this fixes the
regression introduced there as well.

d0d0375375 Remove the remnants of SI_CHEAPCLONE
SI_CHEAPCLONE was introduced in r66067 for use with cloned bpfs. It was
later also used in tty, tun, tap at points. The rough timeline for being
removed in each of these is as follows:

- r181690: bpf switched to use cdevpriv API by ed@
- r181905: ed@ rewrote the TTY later to be mpsafe
- r204464: kib@ removes it from tun/tap, declaring it unused

I've not yet been able to dig up any other consumers in the intervening 9
years. It is no longer set on any devices in the tree and leaves an
interesting situation in make_dev_sv where we're ok with the device already
being set SI_NAMED.

2f4d113ad6 kern_conf: fully initialize cloned devices with make_dev_args, too
Attempting to initialize si_drv{1,2} with mda_si_drv{1,2} does not work if
you are operating on cloned devices.

clone_create must be called prior to the make_dev* family to create/return
the device on the clonelist as needed. This device is later returned early
in newdev(), prior to si_drv{0,1,2} initialization.

This patch simply breaks out of the loop if we've found a device and
finishes init.

ddf6ddca2c ZFS: fix several of the "zpool create" tests
* Remove zpool_create_013_neg.  FreeBSD doesn't have an equivalent of
  Solaris's metadevices.  GEOM would be the equivalent, but since all geoms
  are the same from ZFS's perspective, this test would be redundant with
  zpool_create_012_neg

* Remove zpool_create_014_neg.  FreeBSD does not support swapping to regular
  files.

* Remove zpool_create_016_pos.  This test is redundant with literally every
  other test that creates a disk-backed pool.

* s:/etc/vfstab:/etc/fstab in zpool_create_011_neg

* Delete the VTOC-related portion of zpool_create_008_pos.  FreeBSD doesn't
  use VTOC.

* Replace dumpadm with dumpon and swap with swapon in multiple tests.

* In zpool_create_015_neg, don't require "zpool create -n" to fail.  It's
  reasonable for that variant to succeed, because it doesn't actually open
  the zvol.

* Greatly simplify zpool_create_012_neg.  Make it safer, too, but not
  interfering with the system's regular swap devices.

* Expect zpool_create_011_neg to fail (PR 241070)

* Delete some redundant cleanup steps in various tests

* Remove some unneeeded ATF timeout specifications.  The default is fine.

86daa3cd86 Add CTLFLAG_STATS to all COUNTER_U64* sysctl OIDs
CTLFLAG_STATS identifies a sysctl OID as statistical or informational,
as opposed to a configurable/tunable OID that changes behavior.
This can be used, for example, to verfiy that the kyua tests do not
modify configurable OIDs when allow_sysctl_side_effects is true.

Add CTLFLAG_STATS to all COUNTER_U64* OIDs.

I will add the flag to more OIDs in a few subsequent commits, to
facilitate MFC.  The flag should be added to many more OIDs.  I plan to
add it those that my test found and some nearby that looked obvious.

195cd9b514 nvdimm(4): Add nvdimm_e820 pseudo-bus
nvdimm_e820 is a newbus pseudo driver that looks for "legacy" e820 PRAM
spans and creates ordinary-looking SPA devfs nodes for them
(/dev/nvdimm_spaN).

As these legacy regions lack real NFIT SPA regions and namespace
definitions, they must be administratively sliced up externally using
device.hints.  This is similar in purpose to the Linux memmap= mechanism.

It is assumed that systems with working NFIT tables will not have any use
for this driver, and that that will be the prevailing style going forward,
so if there are no explicit hints provided, this driver does not
automatically create any devices.

0933abded5 tuntap(4): loosen up tunclose restrictions
Realistically, this cannot work. We don't allow the tun to be opened twice,
so it must be done via fd passing, fork, dup, some mechanism like these.
Applications demonstrably do not enforce strict ordering when they're
handing off tun devices, so the parent closing before the child will easily
leave the tun/tap device in a bad state where it can't be destroyed and a
confused user because they did nothing wrong.

Concede that we can't leave the tun/tap device in this kind of state because
of software not playing the TUNSIFPID game, but it is still good to find and
fix this kind of thing to keep ifconfig(8) up-to-date and help ensure good
discipline in tun handling.

It seems reasonable to allow, for instance:

We can unambiguously determine what cert "ce5e74ef.0" refers to, and we've
described it to them in `certctl list` output -- I see little sense in
forcing another level of filesystem inspection to determien what cert file
