Add support for _PDC to the ACPI processor "Performance States library" 
(perflib). If this field is empty, a bogus entry is passed to the _PDC
method so that the default (io) access is returned again. This patch
is partly based on David Moore's patch to
arch/i386/kernel/cpu/cpufreq/acpi.c, sent to the cpufreq mailing list on
June 24th, 2003.

and the ACPI Processor P-States driver.

drivers/acpi/processor.c -- it's the same for all lowlevel drivers.

By doing so, the lowlevel drivers no longer need
to have access to struct acpi_processor.

from Dominik Brodowski

  so that it can be used by various low-level drivers
  (centrino, acpi-io, powernow-k{7,8}, ...)

Fix a horribly wrong memcpy instruction in cpufreq_update_policy which
caused it to oops.

- remove unnecessary usage of flags.performance
- remove double check of _PPC in acpi-cpufreq driver as it's handled in
  drivers/acpi/processor.c already
- remove unneeded EXPORT_SYMBOL
- allocation of memory only for probed CPUs
- add unregistration function to the core
- fix OOPS when PST has core_frequency values of zero
- fix cpufreq_get() output
- fix /proc/acpi/processor/*/performance write support [deprecated]

updates the _PPC handling. It is handled as a CPUfreq
policy notifier which adjusts the maximum CPU speed
according to the current platform limit.

from Dominik Brodowski

The acpi cpufreq driver includes a test at startup which detects whether
ACPI P-States are supported on any CPU, and whether transitions work.
However, this test is faulty: it is only run _after_ the acpi driver is
registered, causing race situations. Also, it doesn't save anything _as_ the
driver is already registered. So, it can safely be removed.

The current algorithm used by Linux ACPI for passive thermal management has
two shortcomings:

- if increasing the CPU processing power as a thermal situation goes away,
  throttling states are decreased later than performance states. This is
  not wise -- it should be the opposite ordering of going "up".

- only if the ACPI CPUfreq driver is used, performance states are used.
  A generalized approach would offer passive cooling even if the ACPI
  P-States cpufreq driver cannot be used (faulty BIOS, FixedHW access, etc.)

The purpose of this release is primarily to update the copyright years
in each module, thus causing a huge number of diffs.  There are a few
small functional changes, however.

Improved error messages when there is a problem finding one or more of
the required base ACPI tables

Reintroduced the definition of APIC_HEADER in actbl.h

Changed definition of MADT_ADDRESS_OVERRIDE to 64 bits (actbl.h)

Removed extraneous reference to NewObj in dsmthdat.c

We must not mark the process TASK_STOPPED early, because
that might allow a signal to wake it up before we actually
got to the "wake_up_forked_process()" state. Total confusion
would happen.

Make wake_up_forked_process() verify the new world order.

Also consolidate a bunch of convoluted if's into a single
"is this an r200 or r300" function.

For a laugh we moved the BSS and our world exploded. Turns out we zero
from __bss_start to _end. Add __bss_stop to our section definitions so
we can use it instead.

Linas Vepstas has audited the ppc64 proc code and found a number of issues.

This fixes loading of modules compiled with debugging on
some platforms.
