4.11 includes a bunch of stack unwinding fixes for microMIPS, but some of those fixes require additional fixup, provided by this series. These patches have been tested on qemu M14Kc micromips and tested for regression on ci40, Boston, Octeon III & malta.
This series is based on mips-for-linux-next Changes in v2: - Keep locals in reverse christmas tree order - Replace conditional with xor and subtract - Refactor is_sp_move_ins to interpret immediate inline.
