memfd_create fds will no longer require an ftruncate(2) to set the size;
they'll grow (to the extent that it's possible) upon write(2)-like syscalls.

Lack of SHM_GROW_ON_WRITE is actively breaking Python's memfd_create tests,
so go ahead and implement it. A future change will make memfd_create always
set SHM_GROW_ON_WRITE, to match Linux behavior and unbreak Python's tests
on -CURRENT.

Currently, "install -s -S" behaviour is inefficient for upgrade.
First it finds that destination file already exists and copies
source file to temporary file. Then it calls strip(1)
with name of temporary file as single agrument and our strip(1) creates
another temporary file in the /tmp (or TMPDIR) making another copy
that is finally copied to DESTDIR third time.
Meantime, strip(1) has an option "-o dst" to specify destination
so install(1) is allowed to skip initial copying from obj to DESTDIR.
This change makes it do so.
Take a look at https://reviews.freebsd.org/D25551 for details
and efficiency numbers (in short: upto 32% gained for installword).

On 32-bit platforms, this expands the shm_size to a 64-bit quantity and
resolves a mismatch between the shmfd size and underlying vm_object size.
The implementation did not account for this kind of mismatch.

INTOFF postpones SIGINT processing and INTON enables it again. This is
important so an interactive shell can return to the top level prompt when
Ctrl+C is pressed.
Given that INTON is automatically done when a builtin completes, the part
where onsig() ignores suppressint when in_dotrap is true is both unnecessary
and unsafe. If the trap is for some other signal than SIGINT, arbitrary code
could have been interrupted.
Historically, INTOFF remained in effect for longer.

While this behaviour is harmless, it is really just an artifact of the
fact that the msgctl(2) implementation uses a user-visible structure as
part of the internal implementation, so it is not deliberate and these
pointers are not useful to userspace. Thus, NULL them out before
copying out, and remove references to them from the manual page.

Communicating with the Raspberry Pi firmware is currently handled by each
driver calling into the mbox driver, however the device tree is structured
such that they should be calling into a firmware driver.
Add a driver for this node with an interface to communicate to the firmware
via the mbox interface.
There is a sysctl to get the firmware revision. This is a unix date so can
be parsed with:
root@generic:~ # date -j -f '%s' sysctl -n dev.bcm2835_firmware.0.revision

Every revision of twsi after the A20 have a bug where we need to
write again the control register after each interrupts. We also need
to add some delay before writing to this register, a simple read of the
same register does the job so do that.
Also fix the case when we have finish sending all the bytes, it only worked
for 1 byte transfer (the same kind that we do for talking to the PMIC on A20
boards).
While here add more debug messages and rework some of them.
This was tested by talking to a AT23C32 eeprom and a DS3231 RTC from an
H3 and A20 board.

* var.c: we need stdint.h on some platforms to get uint32_t
* unit-test/Makefile: we need to supress the specific error
for RE substitution error in modmisc, since it varies accross
different OS.
On some boards there is a lot of of syscon node that are unused as
more specific drivers is probed before, no need to flood the console
for the mostly-unused generic ones.

geli does all of its crypto operations in a separate thread pool, so
g_eli_start, g_eli_read_done, and g_eli_write_done don't actually do very

doubling IOPs on my system. This change does not affect the thread pool.

PR45521: Preserve the value kind when performing a standard
conversion sequence on a glvalue expression.
If the sequence is supposed to perform an lvalue-to-rvalue
conversion, then one will be specified as the first conversion in the
sequence. Otherwise, one should not be invented.
This should fix clang crashing with "can't implicitly cast lvalue to
rvalue with this cast kind", followed by "UNREACHABLE executed at
/usr/src/contrib/llvm-project/clang/lib/Sema/Sema.cpp:538!", when
building recent versions of Ceph, and the CPAN module SYBER/Date-5.2.0.

This patch uses a slightly different algorithm for the non-ext_pgs case,
where a variable called "mcp" is maintained, pointing to the current
location that mbuf data can be filled into. This avoids use of
mtod(mp, char *) + mp->m_len to calculate the location, since this does
not work for ext_pgs mbufs and I think it makes the algorithm more readable.
This change should not result in semantic changes for the non-ext_pgs case.
This is another in the series of commits that add support to the NFS client
and server for building RPC messages in ext_pgs mbufs with anonymous pages.
This is useful so that the entire mbuf list does not need to be
copied before calling sosend() when NFS over TLS is enabled.
Since ND_EXTPG is never set yet, there is no semantic change at this time.
This was a copy-paste bug in r362902. While here, switch to using
${.TARGET}.

This version fixes a regression with regard to tradtional behavior of the
non-standard FreeBSD option "-e". In the previous version "-e quit" caused
bc to exit before any computations had been performed, since all -e option
parameters were concatenated and parsed as a whole, with quit causing the
program to exit as soon as it was parsed. This version parses and executes
commands passed with -e one by one and only exits after all prior commands
have been executed.
This commit is not a SVN merge, since the vendor import had been performed
after the import to contrib. Instead the contents of contrib/bc has been
removed and the new version is copied over unchanged from vendor/bc/dist.
This release fixes a regression from traditional bc behavior in FreeBSD
with regard to "-e quit" being passed on the command line and add Spanish
message catalogs.
