Ideally, you would used MODULE_SYMBOL_PREFIX here, but of course it's a
string. I don't think Kconfig can do arbitrary identifiers, so we can't
make CONFIG_SYMBOL_PREFIX empty or _.
Perhaps clarify it to a bool CONFIG_HAVE_MODULE_UNDERSCORE_PREFIX then,
since that's what you're assuming here?
I made the same assumption in patch 4. The arch defines
CONFIG_HAVE_SYMBOL_PREFIX, which then causes init/Kconfig to define
Mike suggested that I hack kbuild instead, to do something like
unquote = ...
AFLAGS_.tmp_export-asm.o += -DSYMBOL_PREFIX=$(unquote CONFIG_SYMBOL_PREFIX)
I'm experimenting with the idea, but I haven't managed to get it working
