Remove unneeded masks from the arm64 KASAN shadow
When mapping the arm64 KASAN shadow map we use Ln_TABLE_MASK to align
physical addresses, however these should already be aligned either
by rounding to a greater alignment, or the VM subsystem is giving us
a correctly aligned page.
Remove these extra alignment masks.

These feature are required for an upcoming Apple MacBook topcase

A delay after toggling CS is required to avoid anomalies like an extra
junk byte in front of the message. Keeping CS asserted is required to
be able to read a status report after writing a command. (The device
won't return the status if CS was deasserted.)
Sleep is not allowed in the interrupt context where the Apple input

kcsan: add __tsan_mem(cpy|move|set) aliases for clang >= 16
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

Simplify building host tools during DIRDEPS_BUILD
The whole point of the DIRDEPS_BUILD is to avoid tree walks
and basically build everything in a single pass.
We use the pseudo MACHINE "host" to represent the build host.
When the build host is not FreeBSD or is an older version of FreeBSD
it may need some help to build host-tools.
The directory tools/build does this - building libegacy.
local.sys.mk: create a pseudo option MK_host_egacy to indicate
if tools/build needs to be built for "host".
local.dirdeps.mk: set MK_host_egacy.host to ${MK_host_egacy}
all other DEP_MACHINES will get "no"
This allows a Makefile.depend.options in makefs etc to cause tools/build
to be built for host but only if necessary.
local.init.mk: use ISYSTEM as arg to -isystem so that it can be overridden.
The default remains ${STAGE_INCLUDEDIR}
src.init.mk: if MACHINE is host and we are not FreeBSD
set some MK_ flags the same as tools/build/mk/Makefile.boot.pre and
include src.init.${.MAKE.OS:tl}.mk if it exists.
For older versions of FreeBSD add libegacy when building PROGs for "host"
Also instead of -isystem${STAGE_INCLUDEDIR} we want
-I${STAGE_INCLUDEDIR} and -isystem/usr/include so we override ISYSTEM.
This means any headers we stage for "host" will take precedence over
system headers but #include_next will DTRT.
src.init.linux.mk: add
-I${SRCTOP}/tools/build/cross-build/include/linux
and generally deal with building host tools on Linux.
Eg. static linking does not work so set NO_SHARED= no
Override some HAVE_ flags.
src.sys.env.mk: on linux awk throws an warning about # in newvers.sh
just send stderr to /dev/null
The powerpc asm from openzfs assumes that big-endian is always ELFv1 and
ELFv2 is always little-endian, while FreeBSD uses ELFv2 everywhere. Add
the necessary bits to the checksum asm to work on big-endian ELFv2.

tcp: hpts needs to still call output even after input.
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 6cc44223cb6717795afdac4348bbe7e2a968a07d 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).

__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

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

syscall.master: Remove stray 4.2
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

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).

syscall.master: Fix comments

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

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 e68b3792440 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
