Move the checksum functionality out of the main objtool command into a new "objtool klp checksum" subcommand. This has the benefit of making the code (and the patch generation process itself) more modular. For bisectability, both "objtool --checksum" and "objtool klp checksum" work for now. The former will be removed after klp-build has been converted to use the new subcommand. Acked-by: Song Liu <song@kernel.org> Signed-off-by: Josh Poimboeuf <jpoimboe@kernel.org>
