struct acpi_resource_address and struct acpi_resource_extended_address64 share substracts
just at different offsets. To unify the parsing functions, OSPMs like Linux
need a new ACPI_ADDRESS64_ATTRIBUTE as their substructs, so they can
extract the shared data.
This patch also synchronizes the structure changes to the Linux kernel.
The usages are searched by matching the following keywords:
1. acpi_resource_address
2. acpi_resource_extended_address
3. ACPI_RESOURCE_TYPE_ADDRESS
4. ACPI_RESOURCE_TYPE_EXTENDED_ADDRESS
And we found and fixed the usages in the following files:
arch/ia64/kernel/acpi-ext.c
arch/ia64/pci/pci.c
arch/x86/pci/acpi.c
arch/x86/pci/mmconfig-shared.c
drivers/xen/xen-acpi-memhotplug.c
drivers/acpi/acpi_memhotplug.c
drivers/acpi/pci_root.c
drivers/acpi/resource.c
drivers/char/hpet.c
drivers/pnp/pnpacpi/rsparser.c
drivers/hv/vmbus_drv.c
Build tests are passed with defconfig/allnoconfig/allyesconfig and
defconfig+CONFIG_ACPI=n.

For Linux, there are no functional changes/binary generation differences
introduced by this patch.
This change adds a new macro to all files that contain external ACPICA
interfaces. It can be detected and used by the host (via the host-specific
header) for any special processing required for such modules. Lv Zheng.

Add checks for zero-length resource descriptors in all code that
loops through a resource descriptor list. This prevents possible
infinite loops because the length is used to increment the traveral
pointer and detect the end-of-descriptor.

Implements a new interface for walking resource lists that it at

Fixes issues like this:
i_aSL -> iASL
00-7_f -> 00-7F
local_fADT -> local_FADT
execute_oSI -> execute_OSI
Also, in function headers, the parameters are now translated to
lower case (with underscores if necessary.)

These files were relying on module.h to come in via the path
in an include/acpi header file, but we don't want to have
instances of module.h being included from include/* files
if it can be avoided. Have the files include export.h instead.

Add 2010 copyright to all module headers and signons, including
the Linux header. This affects virtually every file in the ACPICA
core subsystem, iASL compiler, and all utilities.
