ACPICA: iASL: Enhancement for constant folding.
ACPICA commit 4f9e950d41cd6f6c704d5d6cf518647620d65e99 Add support to fold expressions with a target operand -- these are folded and converted to a Store operator: Add (4, 3, INT1) --> Store (7, INT1) Also supports ASL+ constructs: INT1 = 4 + 3 --> Store (7, INT1) Linux kernel is not affected by this patch.
