[PATCH v6 20/20] modpost: show offset from symbol for section mismatch warnings

[Masahiro Yamada <masahiroy@kernel.org>]

Currently, modpost only shows the symbol names and section names, so it
repeats the same message if there are multiple relocations in the same
symbol. It is common the relocation spans across multiple instructions.

It is better to show the offset from the symbol.
