Lock vnode after we noticed the VV_ROOT flag.  See comments for
explanation why unlocked check for the flag is considered safe.

Not doing this prevents kernels that do not define LINUX_BOOT_ABI from

2b668041d1 [net80211] extend the net80211 ALQ code to support variable payloads.
Also - allow driver specific bits to be added, rather than just net80211.

This still isn't as useful as it should be by default; it needs to
be a standalone struct/instance so it can be done before net80211
registration occurs, and it can log per-device items.

But, it's getting there.

[AArch64] PR28877: Don't assume we're running after legalization when
  creating vcvtfp2fxs

  Summary:
  The DAG combine transformation that was generating the
  aarch64_neon_vcvtfp2fxs node was assuming that all inputs where legal
  and wasn't accounting that the input could be a v4f64 if we're trying
  to do the transformation before legalization. We now bail out in this
  case.

  All illegal types besides v4f64 were already rejected.

ee9d294b36 [net80211] begin fleshing out new hardware crypto offload features.
* extend the keycache flag word to be 32 bits, not 16 bits
* add new key flags for transmit:
  + IEEE80211_KEY_NOIV: Don't insert IV in the payload when transmitting data frames;
  + IEEE80211_KEY_NOIVMGT:  Don't insert IV in the payload when transmitting MIC frames;
  + IEEE80211_KEY_NOMIC: Don't insert MIC in the payload when transmitting data frames;
  + IEEE80211_KEY_NOMICMGT: don't insert MIC in the payload when transmitting management
    frames.

* teach ieee80211_crypto_demic() about hardware decrypted frames:
  + if frames are hardware decrypted and the frame has failed MIC, treat it as a
     michael failure.
  + if frames are hardware decrypted and the frame has stripped MIC, we can't check the
    MIC in the payload - we don't have anything to compare it against.

This is only part of the work required to successfully transmit/receive
hardware crypto frames such as the qualcomm atheros 11ac offload chips.

There will be further work in the transmit and receive path before this
can be done by default.

b1b6afa587 r295133 attempted to deactivate TSO in the 100Mbit link case with this
adapter to work around bugs in TSO handling at this speed.

em_init_locked is called during first boot of the adapter and will
see that link_speed is unitialized, effectively turning off tso for
all cards at all speeds, which I believe was *not* the intent.

Move the handling of TSO deactivation to the link handler where we can
more effectively make the decision about what to do.  In addition,
completely purge the TSO capabilities instead of disabling just CSUM_TSO.

Thanks to jhb for explanation of the hw capabilites api.

Thanks to royger and cognet for testing the 100Mbit failure case to
ensure that their adapters do indeed still work.

4ad8d73326 Assign a random number to di_gen (for FFS), instead of extracting it
from struct stat.  We don't necessarily have permissions to see the
generation number and the host OS may not have st_gen in struct stat
anyway.  Since the kernel assigns random numbers, there's nothing
meaningful about the generation that requires us to preserve it when
the file system image is created.  With this change, all generation
numbers come from random() and that makes it easier to add support
for reproducible builds at some time in the future (i.e. by adding
an argument to makefs that changes the behaviour of random() so that
it always returns 0 or some predictable sequence).

a304ad90e9 Reduce the bogosity of ministat's % difference calculations.
The previous calculation used an approximation which was only valid in
cases where the means being compared were similar; this resulted in very
odd claims being made, e.g. that 0 +/- 0 is a difference of -100% +/- 1%
from 100 +/- 1.

The new calculation scales sample standard deviations by the means, and
yields approximately correct percentage difference bounds providing that
the reference population is bounded away from zero.  (In the case where
the values being compared are not sufficiently bounded away from zero,
the distribution of ratios becomes much harder to calculate, and is not
likely to be useful anyway.)

Note that when ministat is used for its intended purpose of determining
whether two samples are statistically different, this change is unlikely
to have any noticeable effect; in such cases the means will be similar
enough that the correction applied here will be minimal.

b780b03cbe sed(1): add LEGACY_BSDSED_COMPAT compile-time flag.
In r297602, which included a __FreeBSD_version bump to 1100105, we changed
sed 'i' and 'a' from discarding whitespaces to conform with what GNU and
sysvish sed do.

There are arguments in favor of keeping the old behavior but the new
behavior is also useful for migration purposes. It seems important to at
least consider the case of developers depending on the previous behavior,
so add a CFLAG to enable the old behaviour.

1771e987ca Do not sleep in vm_wait() if pagedaemon did not yet started. Panic instead.
Requests which cannot be satisfied by allocators at boot time often
have unrealizable parameters.  Waiting for the pagedaemon' start would
hang the boot if done in the thread0 context and just never succeed if
executed from another thread.  In fact, for very early stages, sleep
attempt panics with obscure diagnostic about the scheduler state, and
explicit panic in vm_wait() makes the investigation much shorter by
cut off the examination of the thread and scheduler.

Theoretically, some subsystem might grab a resource to exhaustion, and
free it later in the boot process.  If this unlikely scenario does
appear for real, the way to diagnose the trouble can be revisited.
