2015-07-23ACPICA: Namespace: Add function to directly return normalized full pathLv Zheng
ACPICA commit 6e0229bb156d71675f2e07dc7960adb7ec0a60ea This patch adds functions to return normalized full path instead of "external path". The external path contains trailing "_" for each name segment while the normalized full path doesn't contain the trailing "_". Currently this function is used by the method tracing users to specify a none trailing "_" attached name path. Lv Zheng. Note that we need to validate and switch all Linux kernel acpi_get_name() users to use the new name type before removing the old name type from ACPICA.

2014-02-26ACPICA: Headers: Deploy #pragma pack (push) and (pop).Bob Moore
Use push and pop to both guarantee that the correct alignment is used, and to restore the alignment to whatever it was before the header was included. It is reported that the #pragma pack(push/pop) directives are not supported by the specific GCCs, but this patch still doesn't affect kernel build as there are already #pragma pack([1]) directives used in the old ACPICA headers, which means there shouldn't be GCCs that are currently used to compile the ACPI kernels do not support #pragma pack() directives.

If there is only one sub-object, some BIOS code mistakenly simply declares the single object instead of a Package with one sub-object.

2010-07-07ACPICA: Performance enhancement for namespace search and accessAlexey Starikovskiy
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.
