32836259ff ACPI: pci_link: remove acpi_irq_balance_set() interface
This removes the acpi_irq_balance_set() interface from the PCI
interrupt link driver.

x86 used acpi_irq_balance_set() to tell the PCI interrupt link
driver to configure links to minimize IRQ sharing.  But the link
driver can easily figure out whether to turn on IRQ balancing
based on the IRQ model (PIC/IOAPIC/etc), so we can get rid of
that external interface.

It's better for the driver to figure this out at init-time.  If
we set it externally via the x86 code, the interface reduces
modularity, and we depend on the fact that acpi_process_madt()
happens before we process the kernel command line.

56960b546a fujitsu-laptop: Add DMI callback for Lifebook S6420
The Lifebook S6420 is the ICH9M-based follow-up to the S6410. The application panel
contains the following keys: lock, mobility center, eco, info.
Whilst key 4 might be more appropriate for help then key 2, I've done things the
S6410 way. I can confirm that backlight control is functional, and that the lock key
activates the Gnome screensaver as expected.

a0d84a92df ACPI: update debug parameter documentation
Reformat acpi.debug_layer and acpi.debug_level documentation so it's
more readable, add some clues about how to figure out the mask bits that
enable a specific ACPI_DEBUG_PRINT statement, and include some useful
examples.

Move the list of masks to Documentation/acpi/debug.txt (these are
copies of the authoritative values in acoutput.h and acpi_drivers.h).

87b586088e ACPI: turn off all debug output by default
When CONFIG_ACPI_DEBUG=y, the default acpi_dbg_layer and acpi_dbg_level
values built into the ACPI CA have some debug output enabled.  We'd
rather be quiet unless the user actually specified the acpi.debug_level
argument.

This enables distros to ship with CONFIG_ACPI_DEBUG=y without
inundating users with debug output.

afeb12b747 fujitsu-laptop: fix section mismatch warning
Could fix a bug in a hotplug add scenario.

WARNING: drivers/misc/fujitsu-laptop.o(.text+0xbde): Section mismatch in reference from the function acpi_fujitsu_add() to the variable .init.data:fujitsu_dmi_table
The function acpi_fujitsu_add() references
the variable __initdata fujitsu_dmi_table.
This is often because acpi_fujitsu_add lacks a __initdata
annotation or the annotation of fujitsu_dmi_table is wrong.

8950d89aca ACPI: remove CONFIG_ACPI_EC
Remove CONFIG_ACPI_EC.  It was always set the same as CONFIG_ACPI,
and it had no menu label, so there was no way to set it to anything
other than "y".

Per section 6.5.4 of the ACPI 3.0b specification,

    OSPM must make Embedded Controller operation regions, accessed
    via the Embedded Controllers described in ECDT, available before
    executing any control method.

The ECDT table is optional, but if it is present, the above text
means that the EC it describes is a required part of the ACPI
subsystem, so CONFIG_ACPI_EC=n wouldn't make sense.

Remove CONFIG_ACPI_POWER.  It was always set the same as CONFIG_ACPI,
and it had no menu label, so there was no way to set it to anything
other than "y".

The interfaces under CONFIG_ACPI_POWER (acpi_device_sleep_wake(),
acpi_power_transition(), etc) are called unconditionally from the
ACPI core, so we already depend on it always being present.

The SGI Volume Button interface driver uses GPL-only symbols
platform_driver_unregister and platform_driver_register, but
lacks license specification. Thus, when compiled as a module,
this driver cannot be installed. This patch fixes this by
adding the MODULE_LICENSE() specification.

The leds-da903x LED driver was missing the proper #include of

We do need the explict include on other architectures (reported at least
