[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 (These macros have been replaced
by the ACPI_ERROR and ACPI_WARNING macros.)
