so call it ioapic_renumber_irq().

A note to google:
GSI is a Global System Interrupt -- a flat, linear, global IRQ number.

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.
