Makefile: Convert -Wimplicit-fallthrough=3 to just -Wimplicit-fallthrough for clang

2019-08-10T19:45:37Z

A compilation -Wimplicit-fallthrough warning was enabled by commit a035d552a93b ("Makefile: Globally enable fall-through warning") Even though clang 10.0.0 does not currently support this warning without a patch, clang currently does not support a value for this option. Link: https://bugs.llvm.org/show_bug.cgi?id=39382 The gcc default for this warning is 3 so removing the =3 has no effect for gcc and enables the warning for patched versions of clang. Also remove the =3 from an existing use in a parisc Makefile: arch/parisc/math-emu/Makefile Signed-off-by: Joe Perches Reviewed-and-tested-by: Nathan Chancellor Cc: Gustavo A. R.

kbuild: show hint if subdir-y/m is used to visit module Makefile

2019-08-09T16:45:31Z

Since commit ff9b45c55b26 ("kbuild: modpost: read modules.order instead of $(MODVERDIR)/*.mod"), a module is no longer built in the following pattern: [Makefile] subdir-y := some-module [some-module/Makefile] obj-m := some-module.o You cannot write Makefile this way in upstream because modules.order is not correctly generated. subdir-y is used to descend to a sub-directory that builds tools, device trees, etc. For external modules, the modules order does not matter. So, the Makefile above was known to work. I believe the Makefile should be re-written as follows: [Makefile] obj-m := some-module/ [some-module/Makefile] obj-m := some-module.o However, people will have no idea if their Makefile suddenly stops working. In fact, I received questions from multiple people. Show a warning for a while if obj-m is specified in a Makefile visited by subdir-y or subdir-m. I touched the %/ rule to avoid false-positive warnings for the single target. Cc: Jan Kiszka Cc: Tom Stonecypher Signed-off-by: Masahiro Yamada Tested-by: Jan Kiszka

kbuild: revive single target %.ko

2019-08-09T16:40:25Z

I removed the single target %.ko in commit ff9b45c55b26 ("kbuild: modpost: read modules.order instead of $(MODVERDIR)/*.mod") because the modpost stage does not work reliably. For instance, the module dependency, modversion, etc. do not work if we lack symbol information from the other modules. Yet, some people still want to build only one module in their interest, and it may be still useful if it is used within those limitations.
