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.

For static processor driver, boot cmdline:
processor.acpi_cstate_limit=2

For processor module, /etc/modprobe.conf:
options processor acpi_cstate_limit=2

For manual processor module load:
# modprobe processor acpi_cstate_limit=2

From kernel or kernel module:
#include <linux/acpi.h>
acpi_set_cstate_limit(2);

This conflicted with PNP-aware and ACPI-aware drivers,
and required that its exclude-list carry vendor-specific
driver names, which we can't possibly maintain.

With this driver, legacy device drivers (floppy ACPI driver,
COM ACPI driver, and ACPI motherboard driver) which
directly use ACPI can be removed, since now we have unified PNP
interface for legacy ACPI enumerated devices.

Note: ACPI CA is currently undergoing an in-depth and
complete formal evaluation to test/verify the following
areas. Other suggestions are welcome. This will result in
an increase in the frequency of releases and the number
of bug fixes in the next few months.

- Functional tests for all ASL/AML operators
- All implicit/explicit type conversions
- Bit fields and operation regions
- 64-bit math support and 32-bit-only "truncated" math support
- Exceptional conditions, both compiler and interpreter
- Dynamic object deletion and memory leaks
- ACPI 3.0 support when implemented
- External interfaces to the ACPI subsystem

Fixed two alignment issues on 64-bit platforms -
within debug statements in acpi_ev_gpe_detect and
acpi_ev_create_gpe_block. Removed references to the
Address field within the non-aligned ACPI generic address
structure.

Fixed a problem in the Increment and Decrement operators
where incorrect operand resolution could result in the
inadvertent modification of the original integer when the
integer is passed into another method as an argument and
the arg is then incremented/decremented.

Fixed a problem in the FromBCD operator where the upper
32-bits of a 64-bit BCD number were truncated during
conversion.

Fixed a problem in the ToDecimal operator where the length
of the resulting string could be set incorrectly too long
if the input operand was a Buffer object.

Fixed a problem in the Logical operators (LLess,
etc.) where a NULL byte (0) within a buffer would
prematurely terminate a compare between buffer objects.

Added a check for string overflow (>200 characters as per
the ACPI specification) during the Concatenate operator
with two string operands.

Implemented support for the ACPI 3.0 Timer operator. This
ASL function implements a 64-bit timer with 100 nanosecond
granularity.

Defined a new OSL interface, acpi_os_get_timer. This
interface is used to implement the ACPI 3.0 Timer
operator. This allows the host OS to implement the timer
with the best clock available.  Also, it keeps the core
subsystem out of the clock handling business, since the
host OS (usually) performs this function.

Fixed an alignment issue on 64-bit platforms. The
hw_low_level_read/write() functions use a 64-bit address
which is part of the packed ACPI Generic Address
Structure. Since the structure is non-aligned, the
alignment macros are now used to extract the address to
a local variable before use.

Fixed a problem where the ToInteger operator assumed all
input strings were hexadecimal. The operator now handles
both decimal strings and hex strings (prefixed with "0x").

Fixed a problem where the string length in the string
object created as a result of the internal ConvertToString
procedure could be incorrect.  This potentially affected
all implicit conversions and also the ToDecimalString and
ToHexString operators.

Fixed two problems in the ToString operator. If the
length parameter was zero, an incorrect string object was
created and the value of the input length parameter was
inadvertently changed from zero to Ones.

Fixed a problem where the optional ResourceSource string
in the ExtendedIRQ resource macro was ignored.

Simplified the interfaces to the internal division
functions, reducing code size and complexity.
