On some boxes there exist both RSDT and XSDT table. But unfortunately
sometimes there exists the following error when XSDT table is used:
a. 32/64X address mismatch
b. The 32/64X FACS address mismatchIn such case the boot option of "acpi=rsdt" is provided so that
RSDT is tried instead of XSDT table when the system can't work well.http://bugzilla.kernel.org/show_bug.cgi?id=8246

Impact: Reduce memory usage, use new API.
This is part of an effort to reduce structure sizes for machines
configured with large NR_CPUS. cpumask_t gets replaced by
cpumask_var_t, which is either struct cpumask[1] (small NR_CPUS) or
struct cpumask * (large NR_CPUS).(Changes to powernow-k* by .)

This returns the FADT support to the original behavior, which is
to use default register widths. However, now check each register
definition and report a warning if it differs from the default.
This is a first step to moving away from the default widths,
rather than outright believing the widths in all FADTs for all
machines, considered rather dangerous until more data is obtained.Signed-off-by: Bob Moore

1) Update the register lengths for the PM1 event blocks. The
length must be divided by two in order to use these to access
the status registers.
2) Add run-time option to use default register lengths to override a
faulty FADT.
3) Add warning message if any of the X64 address structures contain a length
that does not match the legacy length earlier in the FADT.
4) Move all FADT warning messages into the ValidateFadt function.Signed-off-by: Bob Moore

Changed the acpi_hw_low_level_read and acpi_hw_low_level_write functions to
the public acpi_read and acpi_write to allow direct access to
ACPI registers. Removed the "width" parameter since the width
can be obtained from the input GAS structure. Updated the FADT
initialization to setup the GAS structures with the proper
widths. Some widths are still hardcoded because many FADTs have
incorrect register lengths.Signed-off-by: Bob Moore

Split AcpiSetFirmwareWakingVector into two: one for the 32-bit
vector, another for the 64-bit vector. This is required because the
host OS must setup the wake much differently for each vector (real
vs. protected mode, etc.) and the interface should not be deciding
which vector to use. Also eliminate the GetFirmwareWakingVector
interface, as it served no purpose (only the firmware reads the
vector, OS only writes the vector.) ACPICA BZ 731.http://www.acpica.org/bugzilla/show_bug.cgi?id=731

acpi_early_init() was changed to over-write the cmdline param,
making it really inconvenient to set debug flags at boot-time.Also,
This sets the default level to "info", which is what all the ACPI
drivers use. So to enable messages from drivers, you only have to
supply the "layer" (a.k.a. "component"). For non-"info" ACPI core
and ACPI interpreter messages, you have to supply both level and
layer masks, as before.Signed-off-by: Bjorn Helgaas

This can happen if the _WAK method returns nothing (as per ACPI
1.0) but does return an integer if the implicit return mechanism
is enabled. This is the only method that has this problem,
since it is also defined to return a package of two integers
(ACPI 1.0b+). In all other cases, if a method returns an object
when one was not expected, no warning is issued.Signed-off-by: Bob Moore

This is a reimplemention of commit
0119509c4fbc9adcef1472817fda295334612976
from Matthew GarrettThis 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.http://bugzilla.kernel.org/show_bug.cgi?id=9614

Some of the component definitions that were previous scattered around
