0c9992315e ACPICA: Avoid walking the ACPI Namespace if it is not there 
ACPICA commit b1c3656ef4950098e530be68d4b589584f06cddc

Prevent acpi_ns_walk_namespace() from crashing when called with
start_node equal to ACPI_ROOT_OBJECT if the Namespace has not been
instantiated yet and acpi_gbl_root_node is NULL.

For instance, this can happen if the kernel is run with "acpi=off"
in the command line.

9c0d793945 ACPICA: Cleanup coding style to reduce differences between Linux and ACPICA. 
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 314 lines of 20121018 divergence.diff.

ACPICA core uses ()'s on return statements. This is a known and committed
differences from Linux standard coding style.

This patch cleans up the Linux side ACPICA code to use this codying style
in order to reduce the source code differences between Linux and ACPICA.

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.

The existing interface only has a pre-order callback. This change
adds an additional parameter for a post-order callback which will
be more useful for bus scans. ACPICA BZ 779.

Also update the external calls to acpi_walk_namespace.
