This patch disables the PCI Interrupt Link refernece counts,
which should not co-exist with the 2.6.12 irq_router.resume
method or else a double acpi_pci_link_set() could result
on resume.

Add reference count and disable ACPI PCI Interrupt Link
when no device still uses it.
Warn when drivers have not released Link at suspend time.

Otherwise a platform that supports ACPI based cpufreq
and boots up at lowest possible speed could stay there
forever. This because the governor may request max speed,
but the code doesn't update if there is no change in
speed, and it assumed the initial state of max speed.

EC burst mode benefits many machines, some of
them significantly. However, our current
implementation fails on some machines such
as Rafael's Asus L5D.
This patch restores the alternative EC polling code,
which can be enabled at boot time via "ec_polling"

Fixed three cases in the interpreter where an "index"
argument to an ASL function was still (internally) 32
bits instead of the required 64 bits. This was the Index
argument to the Index, Mid, and Match operators.
The "strupr" function is now permanently local
(acpi_ut_strupr), since this is not a POSIX-defined
function and not present in most kernel-level C
libraries. References to the C library strupr function
have been removed from the headers.
Completed the deployment of static
functions/prototypes. All prototypes with the static
attribute have been moved from the headers to the owning
C file.
ACPICA 20050329 from Bob Moore
An error is now generated if an attempt is made to create
a Buffer Field of length zero (A CreateField with a length
operand of zero.)
The interpreter now issues a warning whenever executable
code at the module level is detected during ACPI table
load. This will give some idea of the prevalence of this
type of code.
Implemented support for references to named objects (other
than control methods) within package objects.
Enhanced package object output for the debug
object. Package objects are now completely dumped, showing
all elements.
Enhanced miscellaneous object output for the debug
object. Any object can now be written to the debug object
(for example, a device object can be written, and the type
of the object will be displayed.)
The "static" qualifier has been added to all local
functions across the core subsystem.
The number of "long" lines (> 80 chars) within the source
has been significantly reduced, by about 1/3.
Cleaned up all header files to ensure that all CA/iASL
functions are prototyped (even static functions) and the
formatting is consistent.
Two new header files have been added, acopcode.h and
acnames.h.
Removed several obsolete functions that were no longer
used.

Implement the framework for binding physical devices
with ACPI devices. A physical bus like PCI bus
should create a 'acpi_bus_type', with:
.find_device:
For device which has parent such as normal PCI devices.
.find_bridge:
It's for special devices, such as PCI root bridge
or IDE controller. Such devices generally haven't a
parent or ->bus. We use the special method
to get an ACPI handle.
Uses new field in struct device: firmware_data

Delete PCI Interrupt Link Device .resume method --
it is the device driver's job to request interrupts,
not the Link's job to remember what the devices want.
This addresses the issue of attempting to run
the ACPI interpreter too early in resume, when
interrupts are still disabled.
