nla_data() cannot return NULL as it simply adds NLA_HDRLEN to the
passed pointer. The NULL pointer check is therefore superfluous.
Remove it.

This patch adds __init to the ACPICA documented initializers:
acpi_initialize_tables()
acpi_initialize_subsystem()
acpi_load_tables()
acpi_enable_subsystem()
acpi_initialize_objects()
and to acpi_reallocate_root_table(), acpi_find_root_pointer() which
are also meant to be called only during initialization.
This patch adds __init to the ACPICA documented finalizer:
acpi_terminate()
as this finalizer is only called in __init function now.
This change helps to reduce source code differences between
ACPICA upstream and Linux.

Add an asmlinkage wrapper around acpi_enter_sleep_state() to prevent
an empty stub from being called by assmebly code for ACPI_REDUCED_HARDWARE
set.
As arch/x86/kernel/acpi/wakeup_xx.S is only compiled when CONFIG_ACPI=y
and there are no users of ACPI_HARDWARE_REDUCED, currently this is in
fact not a real issue, but a cleanup to reduce source code differences
between Linux and ACPICA upstream.

Function acpi_ut_delete_caches() is meant to be used to implement
ACPI_ALLOCATE()/ACPI_FREE() mechanisms in ACPICA, so it should call
acpi_os_free() rather than ACPI_FREE(). Linux is not affected by this
issue as it uses kmem_cache instead of the ACPICA local cache, but
the change helps to reduce source code differences between Linux and
ACPICA upstream.

During the automatic translation of the upstream ACPICA source code
into Linux kernel source code some extra white spaces are added by
the "indent" program at the beginning of each line which is an
invocation of a macro and there is no ";" at the end of the line.
For this reason, a new mode has been added to the translation scripts
to remove the extra spaces inserted before invoking such macros and add
an empty line between the invocations of such macros (like the other
function declarations). This new mode is executed after executing
"indent" during the Linux release process. Consequently, some
existing ACPICA source code in the Linux kernel tree needs to be
adjusted to allow the new scripts to work correctly.
The affected macros and files are:
1. ACPI_HW_DEPENDENT_RETURN (acpixf.h/acdebug.h/acevents.h):
This macro is used as a wrapper for hardware dependent APIs to offer
a stub when the reduced hardware is configured during compilation.
2. ACPI_EXPORT_SYMBOL (utglobal.c):
This macro is used by Linux to export symbols to be found by Linux
modules. All such invocations are well formatted except those
exported as global variables.
This can help to reduce the source code differences between Linux
and upstream ACPICA, and also help to automate the release process.
No functional or binary generation changes should result from it.

interfaces.
This changes can reduce source code differences between Linux and ACPICA
upstream to help improving the release automation.
The side effect of applying this patch in Linux is:
1. Some ACPICA initialization/termination APIs are no longer exported in
Linux, these include:
acpi_load_tables
acpi_initialize_subsystem
acpi_enable_subsystem
acpi_initialize_objects
acpi_terminate
2. This patch does not affect the following APIs as they are currently not
marked with ACPI_EXPORT_SYMBOL in Linux:
acpi_reallocate_root_table
acpi_initialize_tables
Such functions should not be exported as they are internal to ACPI
subsystem in Linux, and will only be invoked inside of ACPI subsystem's
initialization routines marked with __init and termination routines marked
with __exit. While on other OSPMs, such functions may still need to be
exported.
Thus this patch adds the configurability for ACPICA, so that it leaves
OSPMs to determine if the __init/__exit marked functions should be exported
or not. Lv Zheng.

The ACPI spec requires the reset register width to be 8, so we

In the common case, the ACPI_ALLOCATE and related macros now resolve
directly to their respective acpi_os* OSL interfaces. Two options:
1) The ACPI_ALLOCATE_ZEROED macro defaults to a simple local implementation
by default, unless overridden by the USE_NATIVE_ALLOCATE_ZEROED define.
2) For ACPI execution simulation environment (AcpiExec) which is not
shipped with the Linux kernel, the macros can optionally be resolved to
the local interfaces that track each allocation (used to immediately
detect memory leaks).

This change adds and deploys "safe" versions of strcpy and strcat that
ensure that the target buffer does not overflow. These safe functions
are only helpful for processing user input and command lines. For most
ACPICA code however, the required buffer length is precisely calculated
before buffer allocation, so the use of these functions is unnecessary.
ACPICA BZ 1043.
This change only applies to the ACPICA utilities and the debugger, none
of which are not shipped with the kernel yet, so the kernel's behavior
remains unchanged after it.

The original upstream ACPICA change added full history and limited
line editing to the debugger:
This change adds full history and limited line editing for Unix and
Linux systems. It does not use readline() because of portability issues.
Instead it uses the POSIX termio interface to put the terminal in raw
input mode so that the various special keys can be trapped (such as
up-arrow and down-arrow for history support).
Since the debugger is not shipped in the kernel, it only is necessary
to update one header file to keep the kernel source in sync with the
upstream.

Function acpi_processor_load_module() used by the ACPI processor
driver can only really work if the acpi-cpufreq module is available
when acpi_processor_start() is executed which usually is not the case
for systems loading the processor driver module from an initramfs.
Moreover, that used to be a hackish workaround for module autoloading
issues, but udev loads acpi-cpufreq just fine nowadays, so that
function isn't really necessary any more. For this reason, drop
acpi_processor_load_module() entirely.

Specifics:
- Fix for rounding errors in intel_pstate causing CPU utilization to
be underestimated from Brennan Shacklett.
- intel_pstate fix to always use the correct max pstate value when
computing the min pstate from Dirk Brandewie.
- Hibernation fix for deadlocking resume in cases when the probing of
the device containing the image is deferred from Russ Dill.
- acpi-cpufreq fix to prevent the module from staying in memory when
the driver cannot be registered and then attempting to unregister
things that have never been registered on exit"

PM / hibernate: Move software_resume to late_initcall_sync
intel_pstate: Correct calculation of min pstate value
intel_pstate: Improve accuracy by not truncating until final result
