powerpc: Add -Werror at arch/powerpc level Back when I added -Werror in commit ba55bd74360e ("powerpc: Add configurable -Werror for arch/powerpc") I did it by adding it to most of the arch Makefiles. At the time we excluded math-emu, because apparently it didn't build cleanly. But that seems to have been fixed somewhere in the interim. So move the -Werror addition to the top-level of the arch, this saves us from repeating it in every Makefile and means we won't forget to add it to any new sub-dirs.

powerpc: Move core kernel logic into arch/powerpc/Kbuild This is a nice cleanup, arch/powerpc/Makefile is long and messy so moving this out helps a little. It also allows us to do: $ make arch/powerpc Which can be helpful if you just want to compile test some changes to arch code and not link everything. Finally it also gives us a single place to do subdir-cc-flags assignments which affect the whole of arch/powerpc, which we will do in a future patch.

kbuild: use more subdir- for visiting subdirectories while cleaning Documentation/kbuild/makefiles.rst suggests to use "archclean" for cleaning arch/$(SRCARCH)/boot/, but it is not a hard requirement. Since commit d92cc4d51643 ("kbuild: require all architectures to have arch/$(SRCARCH)/Kbuild"), we can use the "subdir- += boot" trick for all architectures. This can take advantage of the parallel option (-j) for "make clean". I also cleaned up the comments in arch/$(SRCARCH)/Makefile. The "archdep" target no longer exists.
