My merged pull request #15557 fixes compilation of sha2 kernels on arm
v5/6. However, the compiler guards only allows sha256/512_armv7_impl to
be used when __ARM_ARCH > 6. This patch enables these ASM kernels on all
arm architectures. Some compiler guards are adjusted accordingly to
avoid the unnecessary compilation of SIMD (e.g., neon, armv8ce) kernels
on old architectures.

If a zvol is renamed, and it has one or more snapshots, and
snapdev=visible is true for the zvol, then the rename causes a kernel
null pointer dereference error. This has the effect (on Linux, anyway)
of killing the z_zvol taskq kthread, with locks still held; which in
turn causes a variety of zvol-related operations afterward to hang
indefinitely (such as udev workers, among other things).
The problem occurs because of an oversight in #15486
(e36ff84c33). As documented in
dataset_kstats_create, some datasets may not actually have kstats
allocated for them; and at least at the present time, this is true for
snapshots. In practical terms, this means that for snapshots,
dk->dk_kstats will be NULL. The dataset_kstats_rename function
introduced in the patch above does not first check whether dk->dk_kstats
is NULL before proceeding, unlike e.g. the nearby
dataset_kstats_update_* functions.
In the very particular circumstance in which a zvol is renamed, AND that
zvol has one or more snapshots, AND that zvol also has snapdev=visible,
zvol_rename_minors_impl will loop over not just the zvol dataset itself,
but each of the zvol's snapshots as well, so that their device nodes
will be renamed as well. This results in dataset_kstats_create being
called for snapshots, where, as we've established, dk->dk_kstats is
NULL.
Fix this by simply adding a NULL check before doing anything in
dataset_kstats_rename.
This still allows the dataset_name kstat value for the zvol to be
updated (as was the intent of the original patch), and merely blocks
attempts by the code to act upon the zvol's non-kstat-having snapshots.
If at some future time, kstats are added for snapshots, then things
should work as intended in that case as well.

ZFS implements copy_file_range(2) using block cloning when possible.
This implementation must respect the RLIMIT_FSIZE limit.
zfs_clone_range() already checks the limit, so it is safe to remove this
check in zfs_freebsd_copy_file_range(). Moreover, the removed check
produces false positives: the length passed to copy_file_range(2) may be
larger than the input file size; as the man page notes, "for best
performance, call copy_file_range() with the largest len value
possible." In particular, some existing code passes SSIZE_MAX there.
The check in zfs_clone_range() clamps the length to the input file's
size before checking, but the removed check uses the caller supplied
length, so something like
$ echo a > /tmp/foo
$ limits -f 1024 cat /tmp/foo > /tmp/bar
fails because FreeBSD's cat(1) uses copy_file_range(2) in the manner
described above.

After c3f2f1aa2, vdev_fault_wanted is set on a vdev after a probe fails.
An end-of-txg async task is charged with actually faulting the vdev.
In a single-disk pool, the probe failure will degrade the last disk, and
then suspend the pool. However, vdev_fault_wanted is not cleared. After
the pool returns, the transaction finishes and the async task runs and
faults the vdev, which suspends the pool again.
The fix is simple: when reopening a vdev, clear the async fault flag. If
the vdev is still failed, the startup probe will quickly notice and
degrade/suspend it again. If not, all is well!

C99 6.7.8.17 says that when an undesignated initialiser is used, only
the first element of a union is initialised. If the first element is not
the largest within the union, how the remaining space is initialised is
up to the compiler.
GCC extends the initialiser to the entire union, while Clang treats the
remainder as padding, and so initialises according to whatever
automatic/implicit initialisation rules are currently active.
When Linux is compiled with CONFIG_INIT_STACK_ALL_PATTERN,
-ftrivial-auto-var-init=pattern is added to the kernel CFLAGS. This flag
sets the policy for automatic/implicit initialisation of variables on
the stack.
Taken together, this means that when compiling under
CONFIG_INIT_STACK_ALL_PATTERN on Clang, the "zero" initialiser will only
zero the first element in a union, and the rest will be filled with a
pattern. This is significant for aes_ctx_t, which in
aes_encrypt_atomic() and aes_decrypt_atomic() is initialised to zero,
but then used as a gcm_ctx_t, which is the fifth element in the union,
and thus gets pattern initialisation. Later, it's assumed to be zero,
resulting in a hang.
As confusing and undiscoverable as it is, by the spec, we are at fault
when we initialise a structure containing a union with the zero
initializer. As such, this commit replaces these uses with an explicit
memset(0).

If multiple threads trip an assertion at the same moment (quite common),
they can be printing at the same time, and their output gets messy.
This adds a simple lock around the whole thing, to prevent a second task
printing assert output before the first has finished.
Additionally, if libspl_assert_ok is not set, abort() is called without
dropping the lock, so that any other asserting tasks will be killed
before starting any output, rather than only getting part-way through.
This is a tradeoff; it's assumed that multiple threads asserting at the
same moment are likely the same fault in different instances of a
thread, and so there won't be any more useful information from the other
tasks anyway.

The "not found" path is attempting to clear SOMELIB_CFLAGS and
SOMELIB_LIBS by resetting them in AC_SUBST(). However, the second arg to
AC_SUBST is expanded in autoconf with `m4_ifvaln([$2], [[$1]=$2])`,
which is defined as "if the first arg is non-empty". The m4 "empty"
construction is [], therefore, the existing AC_SUBST calls never modify
the variables at all.
The effect of this is that leftovers from the library test can leak out.
At least, if a library header is found in the first stage, but the
library itself is not, -lsomelib is added to SOMELIB_LIBS and further
tests done. If that library is not found, SOMELIB_LIBS will not be
cleared.
For most of our library tests this hasn't been a problem, as they're
either always found properly via pkg-config or set directly, or the
calling test immediately aborts configure. For an optional dependency
however, an apparent "partial" result where the header is found but no
corresponding library causes link errors later.
I think a complete fix should probably not be setting SOMELIB_xxx until
the final result is known, but for now, adjusting the AC_SUBST calls to
explictly set the empty shell string (which is not "empty" to m4) at
least restores the intent.
