This is both reasonable and a common GNUism that a lot of ported software
expects.
Universally process \r, \n, and \t into carriage return, newline, and tab
respectively. Newline still doesn't function in contexts where it can't
(e.g. BRE), but we process it anyways rather than passing
UB \n (escaped ordinary) through to the underlying regex engine.
Adding a --posix flag to disable these was considered, but sed.1 already
declares this version of sed a super-set of POSIX specification and this
behavior is the most likely expected when one attempts to use one of these
escape sequences in pattern space.
This differs from pre-r197362 behavior in that we now honor the three
arguably most common escape sequences used with sed(1) and we do so outside
of character classes, too.
Other escape sequences, like \s and \S, will come later when GNU extensions
are added to libregex; sed will likely link against libregex by default,
since the GNU extensions tend to be fairly un-intrusive.

This is a 32-bit structure embedded in each vm_page, consisting mostly
of page queue state. The use of a structure makes it easy to store a
snapshot of a page's queue state in a stack variable and use cmpset
loops to update that state without requiring the page lock.
This change merely adds the structure and updates references to atomic
state fields. No functional change intended.

Summary:
In rS338751, the check to declare `timespec_get()` for C++17 and higher
was incorrectly done against a `cplusplus` define, while it should have
been `__cplusplus`.
Fix this by using `__cplusplus`, and also bump `__FreeBSD_version` so it
becomes possible to correctly check for `timespec_get()` in upstream
libc++ headers.

Partially revert r354741 and r354754 and go back to allocating a
fixed-size chunk of stack space for the auxiliary vector. Keep
sv_copyout_auxargs but change it to accept the address at the end of
the environment vector as an input stack address and no longer
allocate room on the stack. It is now called at the end of
copyout_strings after the argv and environment vectors have been
copied out.
This should fix a regression in r354754 that broke the stack alignment
for newer Linux amd64 binaries (and probably broke Linux arm64 as
well).

of the sensor hardware. Part of the polling process involves signalling
the chip then waiting 20 milliseconds. This was being done with DELAY(),
which is a pretty rude thing to do in a callout. Now a taskqueue_thread
task is scheduled to do the polling, and because sleeping is allowed in
the task context, pause_sbt() replaces DELAY() for the 20ms wait.
r354875 pushed VCBUS <-> ARMC translations to runtime determination, but
incorrectly mapped addresses for the BCM2836 -- SOC_BCM2835 and SOC_BCM2836
are actually mutually exclusive, so the BCM2836 config (GENERIC) would have
taken the latter path in the header and used 0x3f000000 as peripheral start.
Easily fixed -- split out the BCM2836 into its own memmap config and use
that instead if SOC_BCM2836 is included. With this, we get back to userland
again.

This change enables the use of OpenFirmware Console (ofwcons), even when VGA is
available, allowing early kernel messages to be seen, that is important in case
of crashes before VGA console initialization.
This is specially useful in virtualized environments, where the user/developer
doesn't have full control of the virtualization engine (e.g. OpenStack).
The old behavior is preserved by default and, in order to use ofwcons, a few
tunables that have been introduced need to be set:
- hw.ofwfb.disable=1 - disable OFW FrameBuffer device
- machdep.ofw.mtx_spin=1 - change PPC OFW mutex to SPIN type, to match kernel
console's mutex type
- debug.quiesce_ofw=0 - don't call OFW quiesce, needed to keep ofwcons I/O
working

The current vnode layout is not smp-friendly by having frequently read data
avoidably sharing cachelines with very frequently modified fields. In
particular v_iflag inspected for VI_DOOMED can be found in the same line with
v_usecount. Instead make it available in the same cacheline as the v_op, v_data
and v_type which all get read all the time.
v_type is avoidably 4 bytes while the necessary data will easily fit in 1.
Shrinking it frees up 3 bytes, 2 of which get used here to introduce a new
