More specifically your changes to the following files: arch/mips/kernel/pm.c arch/mips/power/cpu.c Don't appear to be necessary with my patch above, but the rest look good to me. With those changes removed: Reviewed-by: James Hogan <james.hogan@xxxxxxxxxx> Build testing of that in progress... Thanks James
