Add support for blacklisting ACPI BIOS implementations by year. By default,
don't use ACPI on BIOS which advertise release years <= 2000. This
can be changed by setting option ACPI_BLACKLIST_YEAR=0 or by setting
acpi_force_load=1.

Sync with HEAD.

Merge T-state a.k.a. throttling support for acpicpu(4).

Remarks:

  1.    Native instructions are supported only on Intel. Native support for
        other x86 vendors will be investigated. By assumption, AMD and others
        use the I/O based approach.

  2.    The existing code, INTEL_ONDEMAND_CLOCKMOD, must be disabled in
        order to use acpicpu(4). Otherwise fatal MSR races may occur.
        Unlike with P-states, no attempt is done to disable the existing
        implementation.

  3.    There is no rationale to export controls to user land.

  4.    Throttling is an artefact from the past. T-states will not be used for
        power management per se. For CPU frequency management, P-states are
        preferred in all circumstances. No noticeable additional power savings
        were observed in various experiments. When the system has been scaled
        to the highest (i.e. lowest power) P-state, it is preferable to move
        from C0 to deeper C-states than it is to actively throttle the CPU.

  5.    But T-states need to be implemented for passive cooling via acpitz(4).
        As specified by ACPI and Intel documents, these can be used as the
        last line of defence against critical thermal conditions. Support
        for this will be added later.

sync with head.

Add P-states. (I blame the ease of using modules.)

Reorganize: also the APIC tables will be dumped in ACPIVERBOSE, and the
callback functions will be modified to be suitable also with other tables.

Merge a driver for ACPI CPUs with basic support for processor power states,
also known as C-states. The code is modular and provides an easy way to add
the remaining functionality later (namely throttling and P-states).

Remarks:

  1.	Commented out in the GENERICs; more testing exposure is needed.

  2.	The C3-state is disabled for the time being because it turns off
	timers, among them the local APIC timer. This may not be universally
	true on all x86 processors; define ACPICPU_ENABLE_C3 to test.

  3.	The algorithm used to choose a power state may need tuning. When
	evaluating the appropriate state, the implementation uses the
	previous sleep time as an indicator. Additional hints would include
	for example the system load.

	Also bus master activity is evaluated when choosing a state. The
	usb(4) stack is notorious for such activity even when unused.
	Typically it must be disabled in order to reach the C3-state,
	but it may also prevent the use of C2.

  4.	While no extensive empirical measurements have been carried out, the
	power savings are somewhere between 1-2 W with C1 and C2, depending
	on the processor, firmware, and load. With C3 even up to 4 W can be
	saved.  The less something ticks, the more power is saved.

Extract ACPIVERBOSE into a kernel module.  The module can be builtin
by defining 'options ACPIVERBOSE' in the kernel config file (no change
from current behavior), or it can be loaded at boot time on those
architectures that support the boot loader's "load" command.

ACPIVERBOSE also includes code to dump acpi/wmi data.

ok jmcneill@

XXX:    This is broken: it calls methods with absolute pathnames (almost
        guaranteed not to be portable across models), it accesses methods
        that are in the domain of other drivers, it walks the namespace on
        its own, it contains plenty of magic constants, it does not
        integrate with existing KPIs, etc. Summa summarum: this should be
        rewritten as a more generic toshiba_acpi(4).

wb(4): Add a driver for Winbond W83L518D SD/MMC readers.

PR# kern/42139: ACPI WMI: new driver

Import acpiwmi(4) from Jukka Ruohonen. From the PR:

Attached is a driver that implements ACPI WMI API:

http://www.microsoft.com/whdc/system/pnppwr/wmi/wmi-acpi.mspx

The WMI is used to provide a generic interface for OEMs to use certain
platform/laptop-specific additions to the standard ACPI in a somewhat
portable way. These can be hotkeys for additional buttons, different event
handlers (wireless kill switch, lid switch, etc.), and so on. At least HP
and Acer use it by default nowadays.

The benefit of this interface would be portability. For an example, instead
of hpqlb(4) that works only with certain HP models, we could have a generic
HP WMI-driver that should work in theory across all HP laptops. On many new
laptops WMI may also be the only way to access laptop/manufacturer-specific
features.

Initial import of an SD/MMC driver for the Winbond W83L518D (and probably
W83L519D) Integrated Media Reader with PNP bus attachment glue.

Rewrite the ACPI Embedded Controller handler to use pure event driven

as AcpiLeaveSleep accesses the interrupt before GPE handling is
restored. The driver uses a kernel thread to handle GPE queries and
mutex/condvar for synchronisation.

Split the ACPI EC into two drivers, one that is attached directly by
acpi.c for the ECDT driven attachment and the normal acpiec for late
attachment. Share almost all code between this two drivers. If acpiecdt
is attached, acpiec is returning. This was discussed with cube@ and is
the best solution so far.

Rework the configuration scheme for PCI fixups:

* bus enumeration fixups are not PCIBIOS-specific, interrupt fixups are done
  by both PCIBIOS and ACPI.  The redundancy is very redundant.  Therefore,
  rename PCIBIOS_*_FIXUP to PCI_*_FIXUP, use PCI_INTR_FIXUP in place of
  ACPI_PCI_FIXUP, and change code refences to match.

* move the fixup defines from opt_pcibios.h to opt_pcifixup.h to reflect
  the above.

* fix up the PCI bus numbering in mainbus_attach(), right after we detect the
  configuration mode.  This probably renders the fixup in pcibios.c
  redundant -- but it should be harmless.

These changes make cardbus work in ACPI-only machines, when PCI_BUS_FIXUP
and PCI_INTR_FIXUP are defined.

Prototype ACPI Control Method Battery driver.

ACPI defines two different battery device interfaces: "Control Method"
batteries, in which AML methods are defined in order to get battery
status and set battery alarm thresholds, and a "Smart Battery" device,
which is an SMbus device accessed through the ACPI Embedded Controller
device; this driver knows how to attach to the former sort of device.

As a total kludge, since we haven't wired things up to sysmon/envsys
yet, we report battery status through a once-per-minute kernel printf,
so don't use this driver yet if you want your disk to spin down.
