Subject: [PATCH v2 0/3] PPC: Fix -Wimplicit-fallthrough for clang
While cleaning up the last few -Wimplicit-fallthrough warnings in tree
for Clang, I noticed
commit 6a9dc5fd6170d ("lib: Revert use of fallthrough pseudo-keyword in lib/")
which seemed to undo a bunch of fixes in lib/ due to breakage in
arch/powerpc/boot/ not including compiler_types.h. We don't need
compiler_types.h for the definition of `fallthrough`, simply
compiler_attributes.h. Include that, revert the revert to lib/, and fix
the last remaining cases I observed for powernv_defconfig.
Changes V1->V2:
* collect tags via b4 (fix Gustavo's tag as per Miguel in patch 2/3).
* reword commit message of patch 1/3 as per Arvind.
* reformat patch 2/3 as per kernel test robot and Gustavo.
