If isc-dhcp44-server is not installed (as is the case the project's CI
servers) we don't create ngctl.shutdown, causing the 'rm' to fail.
That in turn causes the cleanup function to return non-zero, which
causes kyua to consider the test failed.
Use 'rm -f' instead, so we don't error even if the file doesn't exist.

Enhanced REP MOVSB feature of CPUs starting from Ivy Bridge makes
REP MOVSB the fastest way to copy memory in most of cases. However
Intel Optimization Reference Manual says: "setting the DF to force
REP MOVSB to copy bytes from high towards low addresses will expe-
rience significant performance degradation". Measurements on Intel
Cascade Lake and Alder Lake, same as on AMD Zen3 show that it can
drop throughput to as low as 2.5-3.5GB/s, comparing to ~10-30GB/s
of REP MOVSQ or hand-rolled loop, used for non-ERMS CPUs.
This patch keeps ERMS use for forward ordered memory copies, but
removes it for backward overlapped moves where it does not work.
This is just a cosmetic sync with kernel, since libc does not use
ERMS at this time.

When locking the knote list for a socket, we check whether the socket is
a listening socket in order to select the appropriate mutex; a listening
socket uses the socket lock, while data sockets use socket buffer
mutexes.
If SOLISTENING(so) is false and the knote lock routine locks a socket
buffer, then it must re-check whether the socket is a listening socket
since solisten_proto() could have changed the socket's identity while we
were blocked on the socket buffer lock.

During sorted scrub multiple threads (one per vdev) are issuing many
ZIOs same time, all using the same scn->scn_zio_root ZIO as parent.
It causes huge lock contention on the single global lock on that ZIO.
Improve it by introducing per-queue null ZIOs, children to that one,
and using them instead as proxy.
For 12 SSD pool storing 1.5TB of 4KB blocks on 80-core system this
dramatically reduces lock contention and reduces scrub time from 21
minutes down to 12.5, while actual read stages (not scan) are about
3x faster, reaching 100K blocks per second per vdev.

When building modules (as well as the kernel) with ARCH=um, the options
-Dsetjmp=kernel_setjmp and -Dlongjmp=kernel_longjmp are passed to the C
preprocessor for C files. This causes the setjmp and longjmp used in
module/lua/ldo.c to be kernel_setjmp and kernel_longjmp respectively in
the object file. However, the setjmp and longjmp that is intended to be
called is defined in an architecture dependent assembly file under the
directory module/lua/setjmp. Since it is an assembly and not a C file,
the preprocessor define is not given and the names do not change. This
becomes an issue when modpost is trying to create the Module.symvers
and sees no defined symbol for kernel_setjmp and kernel_longjmp. To fix
this, if the macro CONFIG_UML is defined, then setjmp and longjmp
macros are undefined.
When building with ARCH=um for x86 sub-architectures, CONFIG_X86 is not
defined. Instead, CONFIG_UML_X86 is defined. Despite this, the UML x86
sub-architecture can use the same object files as the x86 architectures
because the x86 sub-architecture UML kernel is running with the same
instruction set as CONFIG_X86. So the modules/Kbuild build file is
updated to add the same object files that CONFIG_X86 would add when
CONFIG_UML_X86 is defined.

The check fails in kernels compiled with KASAN because AddressSanitizer
inserts redzones around global variables, so the size of the "kernphys"
symbol is 32 rather than 8. Thus we fall back to copying even though
it's not necessary.
Simply remove the size check. I didn't want to extend the symbol size
check since there's no guarantee that AddressSanitizer will always emit
32 bytes for "kernphys".

When the kernel is compiled with -asan-stack=true, the address sanitizer
will emit inline accesses to the shadow map. In other words, some
shadow map accesses are not intercepted by the KASAN runtime, so they
cannot be disabled even if the runtime is not yet initialized by
kasan_init() at the end of hammer_time().
This went unnoticed because the loader will initialize all PML4 entries
of the bootstrap page table to point to the same PDP page, so early
shadow map accesses do not raise a page fault, though they are silently
corrupting memory. In fact, when the loader does not copy the staging
area, we do get a page fault since in that case only the first and last
PML4Es are populated by the loader. But due to another bug, the loader
always treated KASAN kernels as non-relocatable and thus always copied
the staging area.
It is not really practical to annotate hammer_time() and all callees
with __nosanitizeaddress, so instead add some early initialization which
creates a shadow for the boot stack used by hammer_time(). This is only
needed by KASAN, not by KMSAN, but the shared pmap code handles both.

On arm64, testing pc_curpcb != NULL is not correct since pc_curpcb is
set in pmap_switch() while the bootstrap stack is still in use. As a
result, smp_after_idle_runnable() can free the boot stack prematurely.
Take a different approach: use smp_rendezvous() to wait for all APs to
acknowledge an interrupt. Since APs must not enable interrupts until
they've entered the scheduler, i.e., switched off the boot stack, this
provides the right guarantee without depending as much on the
implementation of cpu_throw(). And, this approach applies to all
platforms, so convert x86 and riscv as well.

This update restores support for suppression of the prompt with -P
when using the libedit or libreadline libraries for command line
editing and history.
libpmc already returns an end address that is after the end of the
last instruction of a function (on both amd64 and arm64) as the end
address written to the annotate map file is computed as the start
address of the symbol plus the size.
Adding one could result in a curious failure where an entire
function's contents in assembly was reduced instead to only the first
instruction. The reason is that when the end instruction is bumped by
one, objdump -d can append the first instruction of the next function
in its output. However, since pmcannotate concatenates all of the
objdump -d output from various functions into a single file which it
then searches to find the assembly for a given file, if this
additional trailer was earlier in the file than the full function, the
trailer was chosen to represent the entire function resulting in the
truncated listing of the function.

Commit acfb506b3d replaced an exit 0 when using -V with a return
instead. FreeBSD's sh treats a return outside of a function like
exit, but this is a non-portable extension. Other Bourne shells only
permit return to be used within a function and continue execution
(possibly with a warning).
To fix, don't reuse VARS_ONLY (which is intended to be set by other
scripts before sourcing newvers.sh directly) and instead use a new
variable (VARS_ONLY_EXIT) to restore the use of exit for the
non-sourced case.
