For increased compatibility with GNU units: support a -v option which
produces more verbose output when spitting out the answer.
GNU -v does additional work in the version, information, and check output which
we do not (yet?) replicate.
and finish the job. ncurses is now the only Makefile in the tree that
uses it since it wasn't a simple mechanical change, and will be
addressed in a future commit.
As per POSIX, the -exec ... {} + primary always returns true, but a non-zero
exit status causes find to return a non-zero exit status itself. GNU does
the same, and also for -execdir ... {} +.
It does not make much sense to return false from the primary only when the
child process happens to be run.
The behaviour for -exec/-execdir ... ; remains unchanged: the primary
returns true or false depending on the exit status, and find's exit status
is unaffected.
The units program is likely little used. It is even less likely that a script
will want the units program to print out its version number by passing -v.
GNU units uses -V for version and -v for verbosity.
Increase compatibility between these two versions (written by the same author)
by switching our flag as well.
Take this opportunity to remove bogus information about the version number and
just call it 'FreeBSD units'.

fts_read() leaves errno unchanged on EOF and sets it on error, so set errno
to 0 before calling it. Also, don't trust finish_execplus() to leave errno
unchanged.
These were originally deleted as "not important" but, actually we need them
in place if we want to be able to use autoconf on software that provides
atf-based tests. (That includes being able to rebuild autotest from scratch
on the Kyua cluster machines, as the automated setup does.)
This is useful for debugging compat modules.

all the SUBDIR entries in parallel, instead of serially. Apply this
option to a selected number of Makefiles, which can greatly speed up the
build on multi-core machines, when using make -j.
This can be extended to more Makefiles later on, whenever they are
verified to work correctly with parallel building.
I tested this on a 24-core machine, with make -j48 buildworld (N = 6):
before stddev after stddev
======= ====== ======= ======
real time 1741.1 16.5 959.8 2.7
user time 12468.7 16.4 14393.0 16.8
sys time 1825.0 54.8 2110.6 22.8
(user+sys)/real 8.2 17.1
E.g. the build was approximately 45% faster in real time. On machines
with less cores, or with lower -j settings, the speedup will not be as
impressive. But at least you can now almost max out a machine with
buildworld!

This targets the existing ARMv6 and ARMv7 SoCs that contain a VFP unit.
This is an optional coprocessors may not be present in all devices, however
it appears to be in all current SoCs we support.
armv6hf targets the VFP variant of the ARM EABI and our copy of gcc is too
old to support this. Because of this there are a number of WITH/WITHOUT
options that are unsupported and must be left as the default value. The
options and their required value are:
* WITH_ARM_EABI
* WITHOUT_GCC
* WITHOUT_GNUCXX
In addition, without an external toolchain, the following need to be left
as their default:
* WITH_CLANG
* WITH_CLANG_IS_CC
As there is a different method of passing float and double values to
functions the ABI is incompatible with existing armv6 binaries. To use
this a full rebuild of world is required. Because no floating point values
are passed into the kernel an armv6 kernel with VFP enabled will work with
an armv6hf userland and vice versa.
Note that these tests are for fmake, not bmake, and thus they are not
installed nor run when bmake is selected (the default). Yes, I have
wasted a *ton* of time on moving tests for no real reason other than
ensuring they are not left behind.
But maybe, just maybe, it was not work in vain: the majority of these
tests also work with bmake and the few that don't may point at broken
stuff. For example, the tests for the "archive" feature do not work
with bmake, but bmake's manpage and source tree seem to imply that they
should. So... to be investigated later; need to poke sjg@.
- Retire long time unused (basically always unused) sys__umtx_lock()
and sys__umtx_unlock() syscalls
- struct umtx and their supporting definitions
- UMUTEX_ERROR_CHECK flag
- Retire UMTX_OP_LOCK/UMTX_OP_UNLOCK from _umtx_op() syscall
__FreeBSD_version is not bumped yet because it is expected that further
breakages to the umtx interface will follow up in the next days.
However there will be a final bump when necessary.

I'm starting with the easy cases. The leftovers need to be looked at a
bit more closely.
Note that this change _does_ modify the code of the old tests. This is
required in order to allow the code to locate the data files in the
source directory instead of the current directory, because Kyua
automatically changes the latter to a temporary directory.
Also note that at least one test is known to be broken here. Actually,
the test is not really broken: it's marked as a TODO but unfortunately
Kyua's TAP parser currently does not understand that. Will have to be
fixed separately.
This change was originally going to only migrate the usr.sbin tests but, as
it turns out, the usr.sbin/sa/ tests require files from usr.bin/lastcomm/
so it's better to just also migrate the latter at the same time. The other
usr.bin tests will be moved separately.
To make these tests work within the test suite, some of them have required
changes to prevent modifying the source directory and instead just rely on
the current directory for file manipulation.
copied to userspace. Failing to do this would result in entries at the bottom
of the ktrdump output to be more recent than entries at the top.
With this change the timestamps are monotonically decreasing going from the
top to the bottom of the ktrdump output.
KTR buffer.
This happens when 'i' tries to wrap around from 0 to 'entries - 1'. Since 'i'
is a signed integer the modulo operation actually returns a negative number.
Fix this by computing the next index to use "by hand" instead of relying
on the modulo operator.
