514d18d79b ACPICA: Update for new Notify values
Implemented several changes for Notify handling: Added support
for new Notify values (ACPI 2.0+) and improved the Notify debug
output. Notify on PowerResource objects is no longer allowed,
as per the ACPI specification.

7a5bb99645 ACPICA: Fix to handle NULL package elements correctly
Fixed problem where NULL package elements were not returned to
the AcpiEvaluateObject interface correctly. Instead of returning a
NULL ACPI_OBJECT package element, the element was simply ignored,
potentially causing a buffer overflow and/or confusing the caller
who expected a fixed number of elements.

1d5b285da1 ACPICA: Fix for resource descriptor optimization issues for _CRS/_SRC
Fixed a problem where resource descriptor size optimization
could cause a problem when a _CRS resource template is passed
to a _SRS method. The _SRS resource template must use the same
descriptors (with the same size) as returned from _CRS. This
change affects the following resource descriptors: IRQ/IRQNoFlags
and StartDependendentFn/StartDependentFnNoPri.

Fixed a regression introduced in version 20071114. The ACPI_HIDWORD

4fcb2fcd4d ACPI, cpuidle: Clarify C-state description in sysfs
Add a new sysfs entry under cpuidle states. desc - can be used by driver to
communicate to userspace any specific information about the state.
This helps in identifying the exact hardware C-states behind the ACPI C-state
definition.

Idea is to export this through powertop, which will help to map the C-state
reported by powertop to actual hardware C-state.

10270d4838 acpi: fix acpi_os_read_pci_configuration() misuse of raw_pci_read()
The raw_pci_read() interface (as the raw_pci_ops->read() before it)
unconditionally fills in a 32-bit integer return value regardless of the
size of the operation requested.

So claiming to take a "void *" is wrong, as is passing in a pointer to
just a byte variable.

Noticed by pageexec when enabling -fstack-protector (which needs other
patches too to actually work, but that's a separate issue).

df92e69599 ACPI: track opregion names to avoid driver resource conflicts.
Small ACPICA extension to be able to store the name of operation regions in osl.c later

In ACPI, AML can define accesses to IO ports and System Memory by Operation
Regions.  Those are not registered as done by PNPACPI using resource templates
(and _CRS/_SRS methods).

The IO ports and System Memory regions may get accessed by arbitrary AML code.
 When native drivers are accessing the same resources bad things can happen
(e.g.  a critical shutdown temperature of 3000 C every 2 months or so).

It is not really possible to register the operation regions via
request_resource, as they often overlap with pnp or other resources (e.g.
statically setup IO resources below 0x100).

This approach stores all Operation Region declarations (IO and System Memory
only) at ACPI table parse time.  It offers a similar functionality like
request_region and let drivers which are known to possibly use the same IO
ports and Memory which are also often used by ACPI (hwmon and i2c) check for
ACPI interference.

A boot parameter acpi_enforce_resources=strict/lax/no is provided, which
is default set to lax:
  - strict: let conflicting drivers fail to load with an error message
  - lax:    let conflicting driver work normal with a warning message
  - no:     no functional change at all
Depending on the feedback and the kind of interferences we see, this
should be set to strict at later time.

Goal of this patch set is:
  - Identify ACPI interferences in bug reports (very hard to reproduce
    and to identify)
  - Find BIOSes for that an ACPI driver should exist for specific HW
    instead of a native one.
  - stability in general

Provide acpi_check_{mem_}region.

Drivers can additionally check against possible ACPI interference by also
invoking this shortly before they call request_region.
If -EBUSY is returned, the driver must not load.
Use acpi_enforce_resources=strict/lax/no options to:
  - strict: let conflicting drivers fail to load with an error message
  - lax:    let conflicting driver work normal with a warning message
  - no:     no functional change at all

1180509f6b ACPI : Update T-state coordination after getting _TSD info
Accordint to ACPI spec, the _TSD object provides T-state control cross
logical processor dependency information to OSPM.
After the _TSD data for all cpus are obtained, OSPM will set up
the T-state coordination between CPUs.

Of course if the _TSD doesn't exist or _TSD data is incorrect , it is
assumed that there is no T-state coordination and T-state is changed
independently.

Now there is no proper solution to update T-state coordination after
one cpu is hotplugged. So this patch won't support hotplugged cpu very well.
