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.

Japanese keyboards traditionally use 0x5c for
both Japanese yen sign key and backslash key.
While a Japanese yen sign is depicted on the keytop,
most of Japanese expect that the scan code 0x7d gives
a backslash (0x5c), not a Japanese yen sign (0xa5).
This is because JIS X 0201 encoding (aka ISO/IEC 646-JA,
an extended version of ASCII which is very popular
in Japan) has Japanese yen sign at 0x5c and
no backslash. On the other hand, ISO/IEC 8859-1
has Japanese yen sign at 0xa5. This difference has
caused a confusion after Unicode became popular since
ISO/IEC 10646 adopted 8859-1 for the plane 0.

Support for NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, NO_MAN, NO_PROFILE,
and NO_WARNS as deprecated in 2014 with a warning added for each one
found. Turn these into error in preperation for removal of compatability
support before FreeBSD 13.
This was previously committed in r354909 and reverted in r355011 due to
unforseen impacts on ports. I've since corrected all amd64 and i386
ports reported in prior runs as well as instance of these variables I
found via grep.
It was saved from the initial purge of drivers in fcp-101 due to being
the onboard Ethernet device on a number of sparc64 machines. Now that
sparc64 is gone, it serves little purpose (PCI cards exist, but are rare
and are unlikely to have been deployed outside Sun systems).

As explained in the comment; GOOGLETEST cannot currently be compiled on any
mips variant at the moment due to the cross toolchain seemingly using the
wrong spec and not pulling in libgcc. We'll be fine when llvm 10 lands, at
which point this should be reverted most expeditiously.
libssp_nonshared.a defines one symbol, __stack_chk_fail_local. This
is used only on i386 and powerpc; other archs emit calls directly to
__stack_chk_fail. Simplify linking on other archs by omitting it.

simple_httpd was granted a reprieve from the picobsd removal based on having
some reported user; it turns out this user isn't actually using the version
in base and merging their changes would be difficult at this point, so the
version in base will simply continue to rot. Retire it now, it may make a
comeback to ports with the improved version.
No notice issued because its current visibility has only been for ~3
months, and a notice has been previously issued about picobsd removal.
This simplifies the driver's rx fast path as well as the bookkeeping

Add a sysctl knob to allow users to re-enable it, and document the knob and
default in cpufreq.4. (While here, add a few unrelated updates to
cpufreq.4.)
It seems that the register value in some hardware simply reflects the
configured P-state. This results in an inadvertent and unintended outcome
where the P-state can only walk down, and then the driver becomes "stuck" in
the slowest possible P-state.
The Linux driver never consults this register, so that's some evidence that
ignoring the contents are relatively harmless.

After r355784 the td_oncpu field is no longer synchronized by the thread
lock, so the stack capture interrupt cannot be delievered precisely.
Fix this using a loop which drops the thread lock and restarts if the
wrong thread was sampled from the stack capture interrupt handler.
Change the implementation to use a regular interrupt instead of an NMI.
Now that we drop the thread lock, there is no advantage to the latter.
Simplify the KPIs. Remove stack_save_td_running() and add a return
value to stack_save_td(). On platforms that do not support stack
capture of running threads, stack_save_td() returns EOPNOTSUPP. If the
target thread is running in user mode, stack_save_td() returns EBUSY.
