3.18-stable review patch. If anyone has any objections, please let me know.
------------------ From: Markos Chandras <[email protected]> commit 98a833c1fa4de0695830f77b2d13fd86693da298 upstream. The "add" instruction is actually a macro in binutils and depending on the size of the immediate it can expand to an "addi" instruction. However, the "addi" instruction traps on overflows which is not something we want on address calculation.
