Hi Linus,
please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release
Two .28 regression fixes.
Some video patches shipping in SuSE that I should have included earlier.
Some EC patches to deal with some out of spec hardware
Some processor fixes for HP's big iron
Some misc stuff
This will update the files shown below.
thanks!

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.

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.

ACPICA: Use spinlock for acpi_{en|dis}able_gpe
Disabling gpe might interfere with gpe detection/handling,
thus producing "interrupt not handled" errors.
Ironically, disabling of GPE from interrupt context is already
under spinlock, so only userspace needs to start using it.

ACPI video: if no ACPI backlight support, use vendor drivers
If an ACPI graphics device supports backlight brightness functions (cmp. with
latest ACPI spec Appendix B), let the ACPI video driver control backlight and
switch backlight control off in vendor specific ACPI drivers (asus_acpi,
thinkpad_acpi, eeepc, fujitsu_laptop, msi_laptop, sony_laptop, acer-wmi).
Currently it is possible to load above drivers and let both poke on the
brightness HW registers, the video and vendor specific ACPI drivers -> bad.
This patch provides the basic support to check for BIOS capabilities before
driver loading time. Driver specific modifications are in separate follow up
patches.
"acpi_backlight=vendor"
Prever vendor driver over ACPI driver for backlight.
"acpi_backlight=video" (default)
Prever ACPI driver over vendor driver for backlight.

ACPI: video: Ignore devices that aren't present in hardware
This is a reimplemention of commit
0119509c4fbc9adcef1472817fda295334612976
from Matthew Garrett <mjg59@...f.ucam.org>
This patch got removed because of a regression: ThinkPads with a
Intel graphics card and an Integrated Graphics Device BIOS implementation
stopped working.
In fact, they only worked because the ACPI device of the discrete, the
wrong one, got used (via int10). So ACPI functions were poking on the wrong
hardware used which is a sever bug.
The next patch provides support for above ThinkPads to be able to
switch brightness via the legacy thinkpad_acpi driver and automatically
detect when to use it.
Original commit message from Matthew Garrett:
Vendors often ship machines with a choice of integrated or discrete
graphics, and use the same DSDT for both. As a result, the ACPI video
module will locate devices that may not exist on this specific platform.
Attempt to determine whether the device exists or not, and abort the
device creation if it doesn't.

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.

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.

ACPI: struct device - replace bus_id with dev_name(), dev_set_name()
This patch is part of a larger patch series which will remove
the "char bus_id[20]" name string from struct device. The device
name is managed in the kobject anyway, and without any size
limitation, and just needlessly copied into "struct device".
To set and read the device name dev_name(dev) and dev_set_name(dev)
must be used. If your code uses static kobjects, which it shouldn't
do, "const char *init_name" can be used to statically provide the
name the registered device should have. At registration time, the
init_name field is cleared, to enforce the use of dev_name(dev) to
access the device name at a later time.
We need to get rid of all occurrences of bus_id in the entire tree
to be able to enable the new interface. Please apply this patch,
and possibly convert any remaining remaining occurrences of bus_id.
We want to submit a patch to -next, which will remove bus_id from
"struct device", to find the remaining pieces to convert, and finally
switch over to the new api, which will remove the 20 bytes array
and does no longer have a size limitation.

ACPI: Behave uniquely based on processor declaration definition type
Associating a Local SAPIC with a processor object is dependent upon the
processor object's definition type. CPUs declared as "Processor" should
use the Local SAPIC's 'processor_id', and CPUs declared as "Device"
should use the 'uid'. Note that for "Processor" declarations, even if a
'_UID' child object exists, it has no bearing with respect to mapping
Local SAPICs (see section 5.2.11.13 - Local SAPIC Structure; "Advanced
Configuration and Power Interface Specification", Revision 3.0b).
This patch changes the lsapic mapping logic to rely on the distinction of
how the processor object was declared - the mapping can't just try both
types of matches regardless of declaration type and rely on one failing
as is currently being done.

ACPI: Disambiguate processor declaration type
Declaring processors in ACPI namespace can be done using either a
"Processor" definition or a "Device" definition (see section 8.4 -
Declaring Processors; "Advanced Configuration and Power Interface
Specification", Revision 3.0b). Currently the two processor
declaration types are conflated.
This patch disambiguates the processor declaration's definition type
enabling subsequent code to behave uniquely based explicitly on the
declaration's type.

ACPI: remove CONFIG_ACPI_EC
Remove CONFIG_ACPI_EC. It was always set the same as CONFIG_ACPI,

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.

ACPI: bugfix reporting of event handler status
Introduce a new flag showing whether the event has an event handler/method.
For all the GPEs and Fixed Events,
1. ACPI_EVENT_FLAG_HANDLE is cleared, it's an "invalid" ACPI event.
2. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_DISABLE are set,
it's "disabled".
3. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_ENABLE are set,
it's "enabled".
4. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_WAKE_ENABLE are set,
it's "wake_enabled".
Among other things, this prevents incorrect reporting of ACPI events
as being "invalid" when it's really just (temporarily) "disabled".

ACPI: fan: Delete the strict check in power transition
On some laptops the Fan device is turned on/off by controlling the
corresponding power resource. For example: If the power resource
defined in _PR0 object is turned off, it indicates that the FAN device
is in off state(the ACPI state is in D3 state).
Maybe the device is already in D3 state and expected to be transited to
D3 state. As there is no _PR3 object, the power transition can't be
finished and it will be switched to the Unknown state.
Maybe it is more reasonable that the strick check in power transistion
is deleted.
