During page fault handling we check the last instruction to understand if the fault was for a read or for a write. By default we fall back to read. New instructions were added to the openrisc 1.1 spec for an atomic load/store pair (l.lwa/l.swa). This patch adds the opcode for l.swa (0x33) allowing it to be treated as a write operation.
