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"

Now that all of the code paths that call acpi_power_off
have been modified to call either call kernel_power_off
(which calls apci_sleep_prepare by way of acpi_shutdown)
or to call acpi_sleep_prepare directly it is redundant to call
acpi_sleep_prepare from acpi_power_off.

So simplify the code and simply don't call acpi_sleep_prepare.

In addition there is a little error handling done so if we
can't register the acpi class we don't hook pm_power_off.

I think I have done the right thing with the CONFIG_PM define
but I'm not certain.  Can this code even be compiled if
CONFIG_PM is false?

machine_power_off on i386 and x86_64 now switch to the
boot cpu out of paranoia and because the MP Specification indicates it
is a good idea on reboot, so for those architectures it is a noop.
I can't see anything in the acpi spec that requires you to be on
the boot cpu to power off the system, so this should not be an issue
for ia64.  In addition ia64 has the altix a massive multi-node
system where switching to the boot cpu sounds insane as we may
hot removed the boot cpu.

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.

Create new interfaces to recursively add an acpi namespace object to the acpi
device list, and recursively start the namespace object.  This is needed for
ACPI based hotplug of a root bridge hierarchy where the add operation must be
performed first and the start operation must be performed separately after the
hot-plugged devices have been properly configured.

When you hot-plug a (root) bridge hierarchy, it may have p2p bridges and
devices attached to it that have not been configured by firmware.  In this
case, we need to configure the devices before starting them.  This patch
separates device start from device scan so that we can introduce the
configuration step in the middle.

I kept the existing semantics for pci_scan_bus() since there are a huge number
of callers to that function.

Also, I have no way of testing the changes I made to the parisc files, so this
needs review by those folks.  Sorry for the massive cross-post, this touches
files in many different places.
