Revert commit b43eac6f33 (ACPICA: iASL: change processing of
external op namespace nodes for correctness; upstream ACPICA
commit aa866a9b4f24bbec9f158d10325b486d7d12d90f).

This was done in order to allow more relaxed usage of ASL external
declarations.

b43eac6f33 ACPICA: iASL: change processing of external op namespace nodes for correctness
ACPICA commit aa866a9b4f24bbec9f158d10325b486d7d12d90f

The declaration External (ABCD.EFGH) creates two nodes in the namespace: ABCD
and EFGH where ABCD is marked as an implicit external node. ABCD is labeled as
implicit because there does not exist a specific External (ABCD) declaration.

Before this change, the declaration External (ABCD.EFGH) and
External (ABCD.EFGH.IJKL) creates the namespace nodes ABCD, EFGH, and IJKL
where ABCD and EFGH are labeled as implicit external nodes. This is incorrect.
The only implicit node should be ABCD because EFGH and IJKL are explicit nodes.
This change fixes the labeling procecess of external op namespace nodes so that
nodes are properly labeled as implicit external.

Due to this commit, the below ASL code results in a compilation error.

0e166e4f67 ACPICA: Debugger: reduce old external path format
ACPICA commit 75c0da9e796bdf9bdd46d75f028a3e1779903214

In the error logs and debugger outputs, use new external path format that
does not contain a trailing underscore.

This patch takes care of acpi_ns_get_external_pathname() invocations, chaning
them into acpi_ns_get_normalized_pathname(TRUE) where possible. Along with some
error log fixes, the following debugger commands are fixed: resources,
handlers, paths. Lv Zheng.

8ea9865577 ACPICA: Namespace: Change namespace override to avoid node deletion
ACPICA commit c0ce529e1fbb8ec47d2522a3aa10f3ab77e16e41

There is no reference counting implemented for struct acpi_namespace_node, so it
is currently not removable during runtime.
This patch changes the namespace override code to keep the old
struct acpi_namespace_node undeleted so that the override mechanism can happen
during runtime. Bob Moore.

ACPICA commit 6084e34e44565c6293f446c0202b5e59b055e351

This patch adds an "NamespaceOverride" flag in struct acpi_walk_state, and allows
namespace objects to be overridden when this flag is set. Lv Zheng.

99567bc550 ACPICA: Update check for setting the ANOBJ_IS_EXTERNAL flag.
The ANOBJ_IS_EXTERNAL flag is only used by an ACPICA utilities - iASL.

No functional change for the Linux kernel should results from applying
this patch, but it helps to reduce source code differences between
the kernel and ACPICA upstream.

56324c1090 ACPICA: Update codes under disabled build options.
This is a cosmetic patch only. Comparison of the resulting binary showed
only line number differences.

This patch does not affect the generation of the Linux binary.
This patch decreases 170 lines of 20121018 divergence.diff.

This patch updates ACPICA codes surrounded by some disabled build options
so that the source code diff between Linux and ACPICA can be reduced.

Some of these build options may never be used in the kernel, so they may
be deleted entirely in future patches.

45dcd31547 Cleanup of invalid ACPI name handling and repair
Implemented a change/cleanup for the handling of invalid ACPI names.
 Names are now validated and repaired only when
 1) entering a new name into the namespace and
 2) disassembling a named AML opcode. A warning is only displayed in
    debug mode or when the interpreter is in "strict" mode, since some
    working machines do in fact contain invalid ACPI names.

c45b5c0970 ACPICA: Performance enhancement for namespace search and access
This change enhances the performance of namespace searches and
walks by adding a backpointer to the parent in each namespace
node. On large namespaces, this change can improve overall ACPI
performance by up to 9X.  Adding a pointer to each namespace node
increases the overall size of the internal namespace by about 5%,
since each namespace entry usually consists of both a namespace
node and an ACPI operand object.
