2ed237af62 Complete commit message for r235024:
Use MADT to match ACPI Processor objects to CPUs.  MADT and DSDT/SSDTs may
list CPUs in different orders, especially for disabled logical cores.  Now
we match ACPI IDs from the MADT with Processor objects, strictly order CPUs
accordingly, and ignore disabled cores.  This prevents us from executing
methods for other CPUs, e. g., _PSS for disabled logical core, which may not
exist.  Unfortunately, it is known that there are a few systems with buggy
BIOSes that do not have unique ACPI IDs for MADT and Processor objects.  To
work around these problems, 'debug.acpi.cpu_unordered' tunable is added.
Set this to a non-zero value to restore the old behavior.
Many thanks to jhb for pointing me to the right direction and the manual
page change.

a30f2b103d The acpi module is no different from others. If it is loaded while the kernel

and no strange behavior.

971f9b29ba Fix things I misadvised to Nate Lawson:
- "Ns No" is redundant, so reduce it to just "Ns";
- use Li to mark up CPU and system power states because here they are
  just strings to be typed literally (add more such mark-up as well);
- the best practice of typesetting tells us to use an en-dash to
  indicate a closed range; fortunately, groff_char(7) provides such a symbol.

In addition, consistently use a comma between independent clauses
coordinated by a conjunction.

ed0911a65e Rework acpi_cpu_idle() to select the next idle state before sleeping, not
after.  Unify the paths for all Cx states.  Remove cpu_idle_busy and
instead do the little profiling we need before re-enabling interrupts.
Use 1 quantum as estimate for C1 sleep duration since the timer interrupt
is the main reason we wake.

While here, change the cx_history sysctl to cx_usage and report statistics
for which idle states were used in terms of percent.  This seems more
intuitive than counters.  Remove the cx_stats structure since it's no
longer used.  Update the man page.

Change various types which do not need explicit size.

507e47381e Make the distinction between sysctl kernel environment variables and
device.hints kernel environment variables when disabling ACPI.

Some users are getting confused when they see hint.acpi.0.disabled.
They are confusing it with a sysctl MIB.

Finally, add a reference for device.hints(5) and kenv(1)
in the "SEE ALSO" section of the man page.

67995bef83 Fix hw.acpi.os_name by renaming it to hw.acpi.osname. The "_name" suffix
is reserved by the loader, and thus any tunable name with that suffix will
be silently discarded.

Document this in the header and man page so that other developers do not
develop so many bumps on the head after banging it against the wall.
