[ACPI] ACPICA 20060317
Implemented the use of a cache object for all internal namespace nodes. Since there are about 1000 static nodes in a typical system, this will decrease memory use for cache implementations that minimize per-allocation overhead (such as a slab allocator.) Removed the reference count mechanism for internal namespace nodes, since it was deemed unnecessary. This reduces the size of each namespace node by about 5%-10% on all platforms. Nodes are now 20 bytes for the 32-bit case, and 32 bytes for the 64-bit case. Optimized several internal data structures to reduce object size on 64-bit platforms by packing data within the 64-bit alignment. This includes the frequently used ACPI_OPERAND_OBJECT, of which there can be ~1000 static instances corresponding to the namespace objects. Added two new strings for the predefined _OSI method: "Windows 2001.1 SP1" and "Windows 2006". Split the allocation tracking mechanism out to a separate file, from utalloc.c to uttrack.c. This mechanism appears to be only useful for application-level code. Kernels may wish to not include uttrack.c in distributions. Removed all remnants of the obsolete ACPI_REPORT_* macros and the associated code. (These macros have been replaced by the ACPI_ERROR and ACPI_WARNING macros.)
