#     sh: Drop -Werror from kernel Makefile
#     
#     Since commit a035d552a93b ("Makefile: Globally enable fall-through
#     warning"), all sh builds fail with errors such as
#     
#     arch/sh/kernel/disassemble.c: In function 'print_sh_insn':
#     arch/sh/kernel/disassemble.c:478:8: error: this statement may fall through
#     
#     Since this effectively disables all build and boot tests for the
#     architecture, let's drop -Werror from the sh kernel Makefile until
#     the problems are fixed.
