MIPS was the last arch to use external toolchain by default but uses
in-tree Clang and lld as of r359233, and now no table entries reference
the footnote.
All FreeBSD archs now use an in-tree toolchain - Clang and ELF Tool
Chain everywhere, and lld everywhere but 32-bit PowerPC (which still
uses ld.bfd). No archs use external toolchain by default.

Now that we have updated the in-tree version of LLVM to 10.0, we have all the
necessary LLVM changes to use Clang+LLD as the default toolchain for MIPS.

The devices supported by these drivers are obsolete ISA cards, and the
sync serial protocols they supported are essentially obsolete too.

Escape sequences like "\n" have to be escaped twice in examples in our
mdoc(7)-based manual pages in order to be displayed properly. The problem
is that otherwise they are interpreted by mdoc(7), which results in:
printf("parent: received '%s'0, buf);
being shown to the user instead of:
printf("parent: received '%s'\n", buf);

It does extremely useful things like execute sendmail and spew dubiously
accurate factoids.
From the feedback, it seems like it is an essential utility in a modern unix

Reverts r358561.
These support outdated or obsolete ISA WAN (T1/E1) sync serial cards,
and these drivers haven't really been touched (other than in tree-wide
sweeps to keep them building) for 15+ years.
Related PCI devices ce and cp are still in the tree, with deprecation
proposed in D23928.

Make style.9 read as a current statement of C99 preferences, rather than a
description of ongoing changes to our preferred style. Alsu use the short
form "ISO C99" on the 2nd and later instances rather than repeating the
unwieldy `ISO/IEC 9899:1999 ("ISO C99")` each time.

ACPI Control Method Batteries have a _BIF and/or _BIX object which
provide static properties of the battery. FreeBSD acpi_cmbat module
supported _BIF object only, which was deprecated as of ACPI 4.0.
_BIX is an extended version of _BIF defined in ACPI 4.0 or later.
As of writing, _BIX has two revisions. One is in ACPI 4.0 (rev.0) and
another is in ACPI 6.0 (rev.1). It seems that hardware vendors still
stick to _BIF only or _BIX rev.0 + _BIF for the maximum compatibility.
Microsoft requires _BIX rev.0 for Windows machines, so there are some
laptop machines with _BIX rev.0 only. In this case, FreeBSD does not
recognize the battery information.
After this change, the acpi_cmbat module gets battery information from
_BIX or _BIF object and internally uses _BIX rev.1 data structure as
the primary information store in the kernel. ACPIIO_BATT_GET_BI[FX]
returns an acpi_bi[fx] structure built by using information obtained
from a _BIF or a _BIX object found on the system. The revision number
field can be used to check which field is available. The acpiconf(8)
utility will show additional information if _BIX is available.
Although ABIs of ACPIIO_BATT_* were changed, the existing APIs for
userland utilities are not changed and the backward-compatible ABIs
are provided. This means that older versions of acpiconf(8) can also
work with the new kernel. The (union acpi_battery_ioctl_arg) was
padded to 256 byte long to avoid another ABI change in the future.
A _BIX object with its revision number >1 will be treated as
compatible with the rev.1 _BIX format.

sparc64 is gone, it serves little purpose (PCI cards exist, but are rare
