ACPI 3.0 support is nearing completion in both the iASL
compiler and the ACPI CA core subsystem.

Fixed a problem in the ToDecimalString operator where the
resulting string length was incorrectly calculated. The
length is now calculated exactly, eliminating incorrect
AE_STRING_LIMIT exceptions.

Fixed a problem in the ToHexString operator to allow a
maximum 200 character string to be produced.

Fixed a problem in the internal string-to-buffer and
buffer-to-buffer copy routine where the length of the
resulting buffer was not truncated to the new size (if
the target buffer already existed).

The low-level field insertion/extraction code (exfldio)
has been completely rewritten to eliminate unnecessary
complexity, bugs, and boundary conditions.

Fixed a problem in the ToInteger, ToBuffer, ToHexString,
and ToDecimalString operators where the input operand could
be inadvertently deleted if no conversion was necessary
(e.g., if the input to ToInteger was an Integer object.)

Fixed a problem with the ToDecimalString and ToHexString
where an incorrect exception code was returned if the
resulting string would be > 200 chars.  AE_STRING_LIMIT is
now returned.

Fixed a problem with the Concatenate operator where AE_OK
was always returned, even if the operation failed.

Fixed a problem in oswinxf (used by AcpiExec and iASL)
to allow > 128 semaphores to be allocated.

Fixed a problem in acpi_ex_convert_to_integer
where new integers were not truncated to 32 bits for
32-bit ACPI tables. This routine converts buffers and
strings to integers.

Implemented support to store a value to an Index() on a
String object.  This is an ACPI 2.0 feature that had not
yet been implemented.

Implemented new behavior for storing objects to individual
package elements (via the Index() operator). The
previous behavior was to invoke the implicit conversion
rules if an object was already present at the index.
The new behavior is to simply delete any existing object
and directly store the new object. Although the ACPI
specification seems unclear on this subject, other ACPI
implementations behave in this manner.  (This is the root
of the AE_BAD_HEX_CONSTANT issue.)

Modified the RSDP memory scan mechanism to support the
extended checksum for ACPI 2.0 (and above) RSDPs. Note
that the search continues until a valid RSDP signature is
found with a valid checksum.

This bubbles all the way up to pci_enable_device().
This allows IRQ0 to be used as a legal PCI device IRQ.

The ES7000 uses an interrupt source override to assign pin20 to IRQ0.
Then platform_rename_gsi assigns pin0 a high-numbered IRQ -- available
for PCI devices.  But IRQ0 needs to be a legal PCI IRQ in the lookup code
to make it as far as the re-name code.

Implemented support for FADT revision 2.  This was an
interim table (between ACPI 1.0 and ACPI 2.0) that adds
support for the FADT reset register.

Implemented optional support to allow uninitialized LocalX
and ArgX variables in a control method.  The variables
are initialized to an Integer object with a value
of zero.  This support is enabled by setting the
acpi_gbl_enable_interpreter_slack flag to TRUE,
which is default unless booted with "acpi=strict".

Implemented support for Integer objects for the SizeOf
operator.  Either 4 or 8 is returned, depending on the
current integer size (32-bit or 64-bit, depending on the
parent table revision).

Fixed a problem in the implementation of the SizeOf and
ObjectType operators where the operand was resolved to
a value too early, causing incorrect return values for
some objects.

Fixed some possible memory leaks during exceptional conditions.

Useful to workaround C3 ipw2100 packet loss,
reducing noise or boot issues on some models.
