ACPICA commit b2294cae776f5a66a7697414b21949d307e6856f
This patch removes unwanted spaces for typedef. This solution doesn't cover
function types.
Note that the linuxize result of this commit is very giant and should have
many conflicts against the current Linux upstream. Thus it is required to
modify the linuxize result of this commit and the commits around it
manually in order to have them merged to the Linux upstream. Since this is
very costy, we should do this only once, and if we can't ensure to do this
only once, we need to revert the Linux code to the wrong indentation result
before merging the linuxize result of this commit. Lv Zheng.

This patch enables ACPICA debugger files using a configurable
CONFIG_ACPI_DEBUGGER configuration item. Those debugger related code that
was originally masked as ACPI_FUTURE_USAGE now gets unmasked.
Necessary OSL stubs are also added in this patch:
1. acpi_os_readable(): This should be arch specific in Linux, while this
patch doesn't introduce real implementation and a complex mechanism to
allow architecture specific acpi_os_readable() to be implemented to
validate the address. It may be done by future commits.
2. acpi_os_get_line(): This is used to obtain debugger command input. This
patch only introduces a simple KDB concept example in it and the
example should be co-working with the code implemented in
acpi_os_printf(). Since this KDB example won't be compiled unless
ENABLE_DEBUGGER is defined and it seems Linux has already stopped to
use ENABLE_DEBUGGER, thus do not expect it can work properly.
This patch also cleans up all other ACPI_FUTURE_USAGE surroundings
accordingly.
1. Since linkage error can be automatically detected, declaration in the
headers needn't be surrounded by ACPI_FUTURE_USAGE.
So only the following separate exported fuction bodies are masked by
this macro (other exported fucntions may have already been masked at
entire module level via drivers/acpi/acpica/Makefile):
acpi_install_exception_handler()
acpi_subsystem_status()
acpi_get_system_info()
acpi_get_statistics()
acpi_install_initialization_handler()
2. Since strip can automatically zap the no-user functions, functions that
are not marked with ACPI_EXPORT_SYMBOL() needn't get surrounded by
ACPI_FUTURE_USAGE.
So the following function which is not used by Linux kernel now won't
get surrounded by this macro:
acpi_ps_get_name()

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.

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.
