ACPI has smart batteries, which work in units of energy and measure
rate of (dis)charge as power, thus it is not appropriate to export it
as a current_now. Current_now will still be exported to allow
for userland applications to match.

Intel graphics hardware that implements the ACPI IGD OpRegion spec
requires that the list of display devices be populated before any ACPI
video methods are called. Detect when this is the case and defer
registration until the opregion code calls it. Fixes crashes on HP

The input/output of _BQC/_BCL/_BCM control methods should be represented

But some buggy _BQC/_BCL/_BCM methods use the index values instead.

Many buggy BIOSes don't export the brightness levels when machine
is on AC/Battery in the _BCL method.
Reformat the _BCL package for these laptops:
now the elements in device->brightness->levels[] are like:
levels[0]: brightness level when on AC power.
levels[1]: brightness level when on Battery power.
levels[2]: supported brightness level 1.
levels[3]: supported brightness level 2.
...
levels[n]: supported brightness level n-1.
levels[n + 1]: supported brightness level n.
So if there are n supported brightness levels on this laptop,
we will have n+2 entries in device->brightnes->levels[].
level[0] and level[1] are invalid on the laptops that don't
export the brightness levels on AC/Battery.
Fortunately, we never use these two values at all, even for the
valid ones.

Due to poor thermal design or Linux driving hardware outside its thermal
envelope, some systems will reach critical temperature and shut down
under high load. This patch adds support for forcing a polling-based
passive trip point if the firmware doesn't provide one. The assumption
is made that the processor is the most practical means to reduce the
dynamic heat generation, so hitting the passive thermal limit will cause
the CPU to be throttled until the temperature stabalises around the
defined value.
UI is provided via a "passive" sysfs entry in the thermal zone
directory. It accepts a decimal value in millidegrees celsius, or "0" to
disable the functionality. Default behaviour is for this functionality
to be disabled.

This patch makes acpi_init() call acpi_wakeup_device_init() directly.
Previously, acpi_wakeup_device_init() was a late_initcall (sequence 7).
acpi_wakeup_device_init() depends on acpi_wakeup_device_list, which
is populated when ACPI devices are enumerated by acpi_init() ->
acpi_scan_init(). Using late_initcall is certainly enough to make
sure acpi_wakeup_device_list is populated, but it is more than
necessary. We can just as easily call acpi_wakeup_device_init()
directly from acpi_init(), which avoids the initcall magic.

This patch makes acpi_init() call acpi_sleep_proc_init() directly.
Previously, acpi_sleep_proc_init() was a late_initcall (sequence 7),
apparently to make sure that the /proc hierarchy already exists:
2003/02/13 12:38:03-06:00 mochel
acpi sleep: demote sleep proc file creation.
- Make acpi_sleep_proc_init() a late_initcall(), and not called from
acpi_sleep_init(). This guarantees that the acpi proc hierarchy is at
least there when we create the dang file.
This should no longer be an issue because acpi_bus_init() (called early
in acpi_init()) creates acpi_root_dir (/proc/acpi).

This patch makes acpi_init() call init_acpi_device_notify() directly.
Previously, init_acpi_device_notify() was an arch_initcall (sequence 3),
so it was called before acpi_init() (a subsys_initcall at sequence 4).
init_acpi_device_notify() sets the platform_notify and
platform_notify_remove function pointers. These pointers
are not used until acpi_init() enumerates ACPI devices in
this path:
acpi_init()
acpi_scan_init()
acpi_bus_scan()
acpi_add_single_object()
acpi_device_register()
device_add()
<use platform_notify>
So it is sufficient to have acpi_init() call init_acpi_device_notify()
directly before it enumerates devices.

Previously, both acpi_init() and acpi_scan_init() were subsys_initcalls,
and acpi_init() was called first based on the link order from the
makefile (bus.o before scan.o).
acpi_scan_init() registers the ACPI bus type, creates the root device,

be done after acpi_init(), and it's better to call acpi_scan_init()
explicitly rather than rely on the link ordering.

Use the 32-bit register addresses whenever they are non-zero. This
means that the 32-bit addresses are favored over the 64-bit
(GAS) addresses. The 64-bit addresses are only used if the 32-bit
addresses are zero. This change provides compatibility with all
versions of Windows. The worst case that this solves is when both
the 32-bit and 64-bit addresses are non-zero, but only the 32-bit
addresses are actually valid. This appears to happen in some
