[ACPI] ACPI source release updated (20020329)

[Grover, A. <and...@in...>]

OK, a new release is on http://sourceforge.net/projects/acpi
<http://sourceforge.net/projects/acpi>  .

While this release should fix some users' problems, I will not be sending it
to Linus, or updating the Intel web site just yet -- immediately prior to
release, we found an issue that required us to always enable
CONFIG_ACPI_DEBUG. Hopefully we can squash that one early next week and then
go all out.

There's also another release of ospmd to play with, but it is still not
ready for prime time (see release notes.)

Regards -- Andy

Summary of changes for this release: 03_29_02

1) ACPI CA Core Subsystem Version 20020329:

Implemented support for late evaluation of TermArg operands
to Buffer and Package objects.  This allows complex
expressions to be used in the declarations of these object
types.

Fixed an ACPI 1.0 compatibility issue when reading Fields.
In ACPI 1.0, if the field was larger than 32 bits, it was
returned as a buffer - otherwise it was returned as an
integer.  In ACPI 2.0, the field is returned as a buffer
only if the field is larger than 64 bits.  The TableRevision
is now considered when making this conversion to avoid
incompatibility with existing ASL code.

Implemented logical addressing for AcpiOsGetRootPointer.
This allows an RSDP with either a logical or physical
address.  With this support, the host OS can now override
all ACPI tables with one logical RSDP.  Includes
implementation of  "typed" pointer support to allow a common
data type for both physical and logical pointers internally.
This required a change to the AcpiOsGetRootPointer
interface.

Implemented the use of ACPI 2.0 Generic Address Structures
for all GPE, Fixed Event, and PM Timer I/O.  This allows the
use of memory mapped I/O for these ACPI features.

Initialization now ignores not only non-required tables (All
tables other than the FADT, FACS, DSDT, and SSDTs), but also
does not validate the table headers of unrecognized tables.

Fixed a problem where a notify handler could only be
installed/removed on an object of type Device.  All "notify"
objects are now supported -- Devices, Processor, Power, and
Thermal.

Removed most verbosity from the ACPI_DB_INFO debug level.
Only critical information is returned when this debug level
is enabled.

Code and Data Size: Current core subsystem library sizes are
shown below.  These are the code and data sizes for the
acpica.lib produced by the Microsoft Visual C++ 6.0
compiler, and these values do not include any ACPI driver or
OSPM code.  The debug version of the code includes the debug
output trace mechanism and has a larger code and data size.
Note that these values will vary depending on the efficiency
of the compiler and the compiler options used during
generation.

2) Linux:

The processor driver (acpi_processor.c) now supports ACPI
2.0-based processor performance control (e.g. Intel(R)
SpeedStep(TM) technology). Note that older laptops that only
have the Intel "applet" interface are not supported through
this.  The 'limit' and 'performance' interface (/proc) are
fully functional.  [Note that basic policy for controlling
performance state transitions will be included in the next
version of ospmd.]  The idle handler was modified to more
aggressively use C2, and PIIX4 errata handling underwent a
complete overhaul (big thanks to Dominik Brodowski).

Added support for ACPI-PCI device binding (acpi_pci_root.c).
_ADR-based devices in the ACPI namespace are now dynamically
bound (associated) with their PCI counterparts (e.g. PCI1-
>01:00.0).  This allows, among other things, ACPI to resolve
bus numbers for subordinate PCI bridges.

Enhanced PCI IRQ routing to get the proper bus number for
_PRT entries defined underneath PCI bridges.

Added IBM 600E to bad bios list due to invalid _ADR value
for PIIX4 PCI-ISA bridge, resulting in improper PCI IRQ
routing.

Partial implementation of full MADT support (e.g. IOAPIC)
for IA32 (acpi.c, mpparse.c).

Added back visual differentiation between fixed-feature and
control-method buttons in dmesg.  Buttons are also subtyped
(e.g. button/power/PWRF) to simplify button identification.

We no longer use -Wno-unused when compiling debug. Please
ignore any "_THIS_MODULE defined but not used" messages.

Can now shut down the system using "magic sysrq" key. (Wolly)
