The code seems to indicate that the invalid mode handlers have different alignment requirements than the valid mode handlers, which puzzles me.

Plain labels, the ENTRY macro, the END macro and the ENDPROC macro are used variously throughout this file, and I wonder if a greater amount of consistency might be attainable. The description of the ENDPROC macro in include/linux/linkage.h makes me think its use might not be completely warranted in blocks of assembly that don't end with a return instruction.

It looks like the error handling here isn't quite complete.
