Question on why specific ELF relocations are supported for module loader

[Russell King - ARM Linux]

Please wrap your message at or before column 72, so I don't have to do that
work for you in order to compose my reply.

Which executable are you referring to?  The only executable is the
kernel binary itself, which is a fully-linked executable (which is
converted to a binary image.)  Modules are not executables, they
are (as Ard correctly pointed out) ELF objects.

You can't execute a module on its own: it requires to be linked to
its kernel in order to become an executable object.
