Restructured the internal HW GPE interfaces to pass/track
the current state of interrupts (enabled/disabled) in
order to avoid possible deadlock and increase flexibility
of the interfaces.

Implemented a "lexicographical compare" for String and
Buffer objects within the logical operators -- LGreater,
LLess, LGreaterEqual, and LLessEqual -- as per further
clarification to the ACPI specification.  Behavior is
similar to C library "strcmp".

Completed a major reduction in CPU stack use for the
acpi_get_firmware_table external function.  In the 32-bit
non-debug case, the stack use has been reduced from 168
bytes to 32 bytes.

Deployed a new run-time configuration flag,
acpi_gbl_enable_interpeter_slack, whose purpose is to allow
the AML interpreter to forgive certain bad AML constructs.
Default setting is FALSE.

Implemented the first use of acpi_gbl_enable_interpeter_slack
in the Field IO support code.  If enabled, it allows field
access to go beyond the end of a region definition if the
field is within the region length rounded up to the next
access width boundary (a common coding error.)

Renamed OSD_HANDLER to acpi_osd_handler, and
OSD_EXECUTION_CALLBACK to acpi_osd_exec_callback for
consistency with other ACPI symbols.  Also, these symbols
are lowercased by the latest version of the acpisrc tool.

The prototypes for the PCI interfaces in acpiosxf.h
have been updated to rename "register" to simply "reg"
to prevent certain compilers from complaining.

General Purpose Event (GPE) from David Shaohua Li

into intel.com:/home/lenb/bk/linux-acpi-test-2.6.7

Implemented support for Buffer and String objects (as
per ACPI 2.0) for the following ASL operators: LEqual,
LGreater, LLess, LGreaterEqual, and LLessEqual.

Completed a new design and implementation for EBDA
(Extended BIOS Data Area) support in the RSDP scan code.
The original code improperly scanned for the EBDA by simply
scanning from memory location 0 to 0x400.  The correct
method is to first obtain the EBDA pointer from within
the BIOS data area, then scan 1K of memory starting at the
EBDA pointer.  There appear to be few if any machines that
place the RSDP in the EBDA, however.

Integrated a fix for a possible fault during evaluation
of BufferField arguments.  Obsolete code that was causing
the problem was removed. (Asus laptop boot crash)

Found and fixed a problem in the Field Support Code
where data could be corrupted on a bit field read that
starts on an aligned boundary but does not end on an
aligned boundary.  Merged the read/write "datum length"
calculation code into a common procedure.

Fixed a problem where hardware GPE enable bits sometimes
not set properly during and after GPE method execution.
Result of ACPICA 20040427 changes.

Removed extra "clear all GPEs" when sleeping/waking.

Removed acpi_ht_enable_gpe and acpi_hw_disable_gpe, replaced
by the single acpi_hw_write_gpe_enable_reg. Changed a couple
of calls to the functions above to the new acpi_ev* calls
as appropriate.

ACPI_OS_NAME was removed from the OS-specific headers.
The default name is now "Microsoft Windows NT" for maximum
compatibility. However this can be changed by modifying
the acconfig.h file.  Fixes EHCI probe issue:
http://bugme.osdl.org/show_bug.cgi?id=1762

Allow a single invocation of acpi_install_notify_handler
for a handler that traps both types of notifies (System,
Device). Use ACPI_ALL_NOTIFY flag.

Run _INI methods on ThermalZone objects. This is against
the ACPI specification, but there is apparently ASL code
in the field that has these _INI methods, and apparently
"other" AML interpreters execute them.

Performed a full 16/32/64 bit lint that resulted in some
small changes.

discovered with IOAPIC disabled.

The problem was that drivers/serial/8250_acpi.c found COM1 in the ACPI
namespace and called acpi_register_gsi() to set up its IRQ.  ACPI tells us
that the COM1 IRQ is edge triggered, active high, but acpi_register_gsi()
was ignoring the edge_level argument, so it blindly set the COM1 IRQ to be
level-triggered.
