I did not bump the date here as the manual page looks more like a draft
and I'm not sure if it is actually up-to-date considering that it's
current Dd dates back to 1998.

The ordering point is not the atomic operation itself, but the load for
acquire or store for release done as part of the atomic. This does not
matter for atomic_load_acq and atomic_store_rel, but does matter for RWM
operations.

We emit a warning if src.conf options WITH_RETPOLINE or INIT_ALL are
in use, and the compiler or linker does not support the feature.
For targets like `cleandir` we skip including bsd.compiler.mk, which
leaves COMPILER_FEATURES unset and spurious warnings were emitted in
early buildworld stages, if these options are in use.
Commit 0837b2ebd5 ("pkg: Die if make -V BRANCH fails") added -W to
usr.sbin/pkg's make flags, causing it to exit on warnings. As a result
buildworld failed when these src.conf options were in use.
Clean this up by omitting the warning if the magic
_NO_INCLUDE_COMPILERMK flag is set, which indicates that
COMPILER_FEATURES is not set.

Tracing bio_bcount makes little sense for some devices like for example
md(4), as it is set to "0" instead of to the actual I/O length.
markj@ suggested the following DTrace one-liner to identify some cases
where bio_length is set but bio_bcount is not:
dtrace -n 'io:::start /args[0]->bio_length != args[0]->bio_bcount/{printf("%d %d", args[0]->bio_length, args[0]->bio_bcount); stack();}'
For future reference in the context of bio_length vs bio_bcount,
phk@ mentioned in the code review that:
> the original intent was to get rid of of bio_bcount

index() and strchr() are implemented by calling strchrnul(), so they
also get to be marked as platform-specific.

Add wrapper inline functions for bus_alloc_resource* that accept a
resource ID by value (instead of a pointer). The rest of the bus
resource API (outside of compat shims) does not accept resource IDs as
arguments, but instead obtains the resource ID from the resource
itself when needed. As such, there is no reason to return any
potentially modified resource IDs to the caller.

The Hifn 7955 & 7956 only supports deprecated & NIST disallowed
algorithms (NIST SP800-224idp): SHA1 and SHA1-HMAC.
Furthermore the entropy RNG of the Hifn 7751, 7951, 7811, 7955,
and 7956 has no NIST Entropy Source Validation (ESV) certificate
and cannot be used in a FIPS-140-3 nor Common Criteara environment.
Furthermore the most prolific instance for FreeBSD was the
Soekris Engineering vpn1201, vpn1211, vpn1401, and vpn1411
offerings. These are all 32-bit only processors. The i386
kernel was de-supported in 15.0.

The comment in sys/vnode.h describes
the v_op member as "vnode operations vector",
so use "operations" instead of "operation" here.
