MIPS: microMIPS: Add support for exception handling.
All exceptions must be taken in microMIPS mode, never in classic MIPS mode or the kernel falls apart. A few NOP instructions are used to maintain the correct alignment of microMIPS versions of the exception vectors. Signed-off-by: Steven J. Hill <Steven.Hill@imgtec.com>
