This appears to be a copy-and-paste error that has simply been
overlooked. The tree contains only two calls to any of the affected
variants, but recent additions to the test suite started exercising the
call to atomic_clear_rel_int() in ng_leave_write(), reliably causing
panics.
Apparently, the issue was inherited from the arm64 atomic header. That
instance was addressed in c90baf6817, but the fix did not make its way
to RISC-V.
Note that the particular test case ng_macfilter_test:main still appears
to fail on this platform, but this change reduces the panic to a
timeout.

Clang commit ccb4124a4172bf2cb2e1cd7c253f0f1654fce294:
Fix -gz=zlib options for linker
gcc translates -gz=zlib to --compress-debug-options=zlib for both
assembler and linker but clang only does this for assembler.
The linker needs --compress-debug-options=zlib option to compress the
debug sections in the generated executable or shared library.
Due to this bug, -gz=zlib has no effect on the generated executable or
shared library.
This patch fixes that.

In some configurations we need more classes than ALTQ supports by
default. Increase the maximum number of classes we allow.
This will only cost us a comparatively trivial amount of memory, so
there's little reason not to do so.
If ever we find we want even more we may want to consider turning these
defines into a tunable, but for now do the easy thing.

Recent changes have made it such that attaching to a jail will augment
the attaching process' cpu mask with the jail's cpuset. While this is
convenient for allowing the administrator to cpuset arbitrary programs
that will attach to a jail, this is decidedly not convenient for
executing long-running daemons during jail creation.
This change inserts a reset of the process cpuset to the root cpuset
between the fork and attach to execute a command. This allows commands
executed to have the widest mask possible, and the administrator can
cpuset(1) it back down inside the jail as needed.
With this applied, one should be able to change a jail's cpuset at
exec.poststart in addition to exec.created. The former was made
difficult if jail(8) itself was running with a constrained set, as then
some processes may have been spawned inside the jail with a non-root
set. The latter is the preferred option so that processes starting in
the jail are constrained appropriately up front.
Note that all system commands are still run with the process' initial
cpuset applied.

This change is a refactoring cleanup to improve support for compat32
syscalls (and compat64 on CHERI systems). Each process ABI now has it's
own struct sycall instead of using one global list. The list of all
syscalls is replaced with a list of seen syscalls. Looking up the syscall
argument passing convention now interates over the fixed-size array instead
of using a link-list that's populated on startup so we no longer need the
init_syscall() function.
The actual functional changes are in D27625.

In 48ba9b2669 we switched from creating level 1 blocks to smaller
level 2 blocks when creating the early arm64 page tables. On issue
was that they had a different meaning for register x7. The former used
it to hold page table attributes, while the latter held just the memory
type. This caused these attributes to be incorrectly shifted.
Fix this by changing the meaning of x7 to hold the block attributes
and fix the only caller that used the old meaning.
Most hardware seems to have handled the bits being off however qemu
failed to boot as reserved bits that should be zero were being set and
qemu fails to clear these when translating from a virtual address to a
physical address.

Without this change, an entry like:

will fail, as the shell will try to execute (' -n true'), while an entry like:
* * * * * username -n true # One space between username and option.
works as expected (executes 'true').
For user crontabs, this is not an issue as the preceding (day of week
