The patch reduces source code differences between the Linux kernel and the ACPICA upstream so that the linuxized ACPICA 20151218 release can be applied with reduced human intervention. The pscode.c has already been out of sync for months, and it becomes more and more difficult to merge pscode.c changes, so instead of update the affected lines of pscode.c, this patch synchronizes entire pscode.c file.
