ACPICA 20050408 from Bob Moore
Fixed three cases in the interpreter where an "index" argument to an ASL function was still (internally) 32 bits instead of the required 64 bits. This was the Index argument to the Index, Mid, and Match operators. The "strupr" function is now permanently local (acpi_ut_strupr), since this is not a POSIX-defined function and not present in most kernel-level C libraries. References to the C library strupr function have been removed from the headers. Completed the deployment of static functions/prototypes. All prototypes with the static attribute have been moved from the headers to the owning C file. ACPICA 20050329 from Bob Moore An error is now generated if an attempt is made to create a Buffer Field of length zero (A CreateField with a length operand of zero.) The interpreter now issues a warning whenever executable code at the module level is detected during ACPI table load. This will give some idea of the prevalence of this type of code. Implemented support for references to named objects (other than control methods) within package objects. Enhanced package object output for the debug object. Package objects are now completely dumped, showing all elements. Enhanced miscellaneous object output for the debug object. Any object can now be written to the debug object (for example, a device object can be written, and the type of the object will be displayed.) The "static" qualifier has been added to all local functions across the core subsystem. The number of "long" lines (> 80 chars) within the source has been significantly reduced, by about 1/3. Cleaned up all header files to ensure that all CA/iASL functions are prototyped (even static functions) and the formatting is consistent. Two new header files have been added, acopcode.h and acnames.h. Removed several obsolete functions that were no longer used. Signed-off-by: Len Brown <len.brown@intel.com>
