Not sure you are proposing this as part of your patch set. I suggest
that you don't and post this separately.

Also, the removal of kallsyms.h from ftrace.h should be a totally
separate patch (along fixing anything that breaks when you remove it,
if C files were using ftrace.h to pull in kallsyms.h for them).

Then the addition of modules.h to kallsyms.h should be a separate
patch. And you should compile the kernel with both a make allmodconfig,
make allyesconfig, and then make allyesconfig but disable modules, and
see if anything breaks.
