Any other native driver using BUS_PROBE_DEFAULT will attach

Summary:
After https://github.com/llvm/llvm-project/commit/b4257d3bf58c ("[tsan]
Replace mem intrinsics with calls to interceptors") intrinsic calls to
memcpy, memmove or memset will directly call sanitizer interceptors,
e.g. __tsan_memcpy, __tsan_memmove or __tsan_memset.
Building GENERIC-KCSAN with clang >= 16 would thus result in link errors
similar to:
ld: error: undefined symbol: __tsan_memcpy
>>> referenced by cam_compat.c:150 (/usr/src/sys/cam/cam_compat.c:150)
>>> cam_compat.o:(cam_compat_handle_0x17)

>>> referenced by cam_compat.c:152 (/usr/src/sys/cam/cam_compat.c:152)
>>> cam_compat.o:(cam_compat_handle_0x17)
>>> referenced 1692 more times
Similar to subr_msan.c, add aliases from the existing kcsan_* versions
of these functions to __tsan_* names.

It appears that PAC registers are configured to trap upon access, but
since the kernel starts in EL1 on this platform it has no ability to
inspect or modify this configuration. Simply disable PAC on this

The other stacks it turns out actually expect the output to be called and can become stuck if it is
not. This is because they run there timer code from there and the input routine does not always
assure a timer is running. The real longterm fix here might be to go into the other stacks (rack and bbr)
and make sure that a timer is running after input if you don't do output.. as well as call the timer functions.
This would cut down on calls from hpts. But I think its too dramatic of a change for the immediate time.

Before the commit 6cc44223cb the
field event_mask was fully copied to the EventMasks field.
After this commit the event_mask (uint8_t) is 4 times casted to
EventMask (uint32_t). Because of that 24 bits of each event_mask array
is lost.
This commits brings back simple copying of field, and after words
converting 32 bits field to the requested endian.
I don't think we need more sophisticated method,
as the array is of size 4 (for 32 bits version).

Commit 3e0856b63f updated
__sg_alloc_table_from_pages to use the same API as linux, but modified
the loop condition when going over the pages in a sg list. Part of the
change included moving the sg_next call out of the for loop and into the
body, which causes an off by one error when traversing the list. Since
sg_next is called before the loop body it will skip the first element
and read one past the last element.
This caused panics when running PRIME with nvidia-drm as the off-by-one
issue causes a NULL dereference.

The 4.2 sigreturn was a bit of a enima so the 4.2 was remove. Regenerate
to cope the very minor changes in comments and one string.
Sponsored by: Netflix
Back in 4.3BSD, the system call table wasn't generated, and there was an
entry:
"4.2 sigreturn", /* 139 = old 4.2 sigreturn */
This got converted to
139 OBSOL 0 4.2 sigreturn
in 4.3 RENO. Since it was obsolete, nothing bad happened. In fact,
there was code in makeyscalls.sh to cope:
{ comment = $4
for (i = 5; i <= NF; i++)
comment = comment " " $i
if (NF < 5)
$5 = $4
}
so the generated comment in syscalls.c was almost correct:
"obs_4.2", /* 139 = obsolete 4.2 sigreturn */
a bug that we have to this very day, despite makesyscalls.sh being
rewritten in lua.
However, this historical wart is the only place in our current
syscalls.master file where we have an extra field for the 'not
generated' class of system calls. Remove the historical wart so that the
re-write of makesyscalls.lua can be simpler (so, I hope, qemu's bsd-user
can large swathes of code automatically generated too). This should help
make things more understandable (changes to simplify makesyscalls.lue
aren't quite debugged, so have to wait for another day).
There's 3 different obsolete sigreturns (but only 1 that was ever in
FreeBSD 2.x and newer).

Have more accruate comments. While #if, #else, etc are copied to the
header files, lines that don't start with # are not. And #include files
are only output to sysinc (which winds up at the front of init_sysent.c
which seems a bit odd). This is all radically undocumented, and likely
has drifted somewhat from 4.4BSD and what other systems do (they've
drifted too, fwiw).

This change touches both kernel and netstat(1), but either of the changes
will fix printing pcb addresses with -A.
The thing is that historically netstat(1) treated TCP differently, and
printed tcpcb address instead of inpcb address. This is not documented
anywhere! With e68b379244 these two addresses became the same. It is
highly likely they will be the same for a long time, but it might be they
will start to differ again in a far future. My proposal is to stop
treating TCP differently with netstat(1) and right now is a good opportunity
to do that, since there will be no behavior change at all. The kernel
change to tcp_inptoxtp() will go into stable/14 to make it compatible with
netstat(1) binary from stable/13. We can drop it later, probably together
with in_ppcb pointer from inpcb. The in_ppcb in xinpcb will stay for size
compatibility.
