kbuild: fail kernel compilation in case of unresolved module symbols
At stage 2 modpost utility is used to check modules. In case of unresolved
symbols modpost only prints warning.
IMHO it is a good idea to fail compilation process in case of unresolved
symbols (at least in modules coming with kernel), since usually such errors
are left unnoticed, but kernel modules are broken.
- new option '-w' is added to modpost:
if option is specified, modpost only warns about unresolved symbols
- modpost is called with '-w' for external modules in Makefile.modpost
