Only remove it for those that need it for MODULE_NAME_LEN because it
was used in KSYM_SYMBOL_LEN. But not the rest. Lots of these files use
module code directly. Now you made it require kallsyms.h to get to that
code. If for some reason we no longer need kallsyms.h, or that
kallsyms.h no longer needs module.h, these files will not build.

If code uses module code, it must include module.h.

So NACK for this patch.

To see what needs module.h, before reverting this patch, remove the
module.h from kallsyms.h, and also remove the MODULE_NAME_LEN from it as
well. Compile all the tracing code, and see what does not build. Those
files will be the ones that you need to add back the module.h to.
