33dc8ca368 Document newly added loader tunables "hw.acpi.install_interface" and 
"hw.acpi.remove_interface".

eb994eb349 Use AcpiReset() from ACPICA instead of rolling our own, which is actually 
incomplete.  If FADT says the register is available, enable the capability
by default.  Remove the previous default value from acpi(4).

a30f2b103d The acpi module is no different from others. If it is loaded while the kernel 
has it compiled in, it will be rejected with "module acpi already present!"
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.
