Not really "all".

powerpc:85xx/sbc8548_defconfig:

arch/powerpc/kernel/align.c: In function ‘emulate_spe’:
arch/powerpc/kernel/align.c:178:8: error: this statement may fall through

Plus many more similar errors in the same file.

All sh builds:

arch/sh/kernel/disassemble.c: In function 'print_sh_insn':
arch/sh/kernel/disassemble.c:478:8: error: this statement may fall through

Again, this is seen in several places.

mips:cavium_octeon_defconfig:

arch/mips/cavium-octeon/octeon-usb.c: In function 'dwc3_octeon_clocks_start':
include/linux/device.h:1499:2: error: this statement may fall through

None of those are from recent changes. And this is just from my small
subset of test builds.
