If we fail noise floor calibration then we may end up with a deaf NIC
which we can't recover without a full chip reset.
Earlier chips seem to get less stuck in this condition versus AR9280/later
and AR9300/later, but whilst here just fix up the AR5212 era chips to also
return NF calibration failures.
This HAL routine would only return failure if the channel was not configured.
This is a no-op until the driver side code for doing resets and the HAL
code for being told about the reset type (and then handling it!) is
implemented.
Tested:
* AR9280, STA mode
* AR2425, STA mode
* AR9380, STA mode
Plenty of allocation sites pass M_ZERO and sizes which are small and known
at compilation time. Handling them internally in malloc loses this information
and results in avoidable calls to memset.
Instead, let the compiler take the advantage of it whenever possible.
Discussed with: jeff
I'm in the process of reworking how the reset path works with an eye
to better recovery when the chips hang and/or go RF/PHY deaf.
This is the first step in a lot of unification and API changes.
* Change ena-com BIT macro to work on unsigned value.
To make the shifting operations safer, they should be working on
unsigned values.
* Fix a mutex not owned ASSERT panic in ENA control path.
A thread calling cv_broadcast()/cv_signal() must hold the mutex used for
cv_wait(). Fix the ENA control path code that has this problem.

The upstream repository is on github BLAKE2/libb2. Files landed in
sys/contrib/libb2 are the unmodified upstream files, except for one
difference: secure_zero_memory's contents have been replaced with
explicit_bzero() only because the previous implementation broke powerpc
link. Preferential use of explicit_bzero() is in progress upstream, so
it is anticipated we will be able to drop this diff in the future.
sys/crypto/blake2 contains the source files needed to port libb2 to our
build system, a wrapped (limited) variant of the algorithm to match the API
of our auth_transform softcrypto abstraction, incorporation into the Open
Crypto Framework (OCF) cryptosoft(4) driver, as well as an x86 SSE/AVX
accelerated OCF driver, blake2(4).
Optimized variants of blake2 are compiled for a number of x86 machines
(anything from SSE2 to AVX + XOP). On those machines, FPU context will need
to be explicitly saved before using blake2(4)-provided algorithms directly.
Use via cryptodev / OCF saves FPU state automatically, and use via the
auth_transform softcrypto abstraction does not use FPU.
The intent of the OCF driver is mostly to enable testing in userspace via
/dev/crypto. ATF tests are added with published KAT test vectors to
validate correctness.

Defaulting to CK_MD_RMO has the unfortunate side effect of generating
memory barriers that are useless on those arches, and the even more
unfortunate side effect of generating lfence/sfence/mfence on i386, even
if older CPUs don't support it.
This should fix the panic reported when using IPFW on a Pentium 3.
Note that mfence and sfence might still be used in a few case, but that
shouldn't happen in FreeBSD right now, and should be fixed upstream first.

IVRS can have entry of type legacy and non-legacy present at same time for same AMD-Vi device. ivhd driver will ignore legacy if new IVHD type is present as specified in AMD-Vi specification. Earlier both of IVHD entries used and two ivhd devices were created.

libfdt highlights since 1.4.3:
- fdt_property_placeholder added to create a property without specifying its
value at creation time
- stringlist helper functions added to libfdt
- Improved overlay support
- Various internal cleanup
Also switch stand/fdt over to using libfdt for overlay support with this
update. Our current overlay implementation works only for limited use cases
with overlays generated only by some specific versions of our dtc(1). Swap
it out for the libfdt implementation, which supports any properly generated
overlay being applied to a properly generated base.
This will be followed up fairly soon with an update to dtc(1) in tree to
properly generate overlays.
MFC note: the <stdlib.h> include this update introduces in libfdt_env.h is
apparently not necessary in the context we use this in. It's not immediately
clear to me the motivation for it being introduced, but it came in with
overlay support. I've left it in for the sake of accuracy and because it's
not harmful here on HEAD, but MFC'ing this to stable/11 will require
wrapping the #include in an `#ifndef _STANDALONE` block or else it will
cause build failures.

This is in contrib code but since we only have mallocarray(9) in current
we will not upstream this.
This effectively brings back r327934, which was reverted to correct the
log message.
Add an implementation of the intrinsics invoked by __builtin_ctz{,ll} and
__builtin_clz{,ll}, and include this compilation unit on platforms that lack
assembly intrinsics for those builtins (MIPS and RISC-V).
Future cleanup work might involve bringing these into a mini libcompiler-rt
for the standalone kernel environment. Or cleaning up the approach upstream
takes for builtins in standalone environments (or just FreeBSD). For now,
at least this builds, and doesn't require modifying the vendor code.

This necessitated refactoring state seed allocation from

as it is now also used by ipf_state_rehash() when changing the size of

According to Christos Zoulas <christos@NetBSD.org>:
The bug was encountered by a NetBSD vendor who's customer machines had
