Currently, using llvm-objtool, this script just silently succeeds without actually do the intended checking. So this updates it to work properly. Firstly, llvm-objdump does not add target symbol names to the end of branches in its asm output, so we have to drop the branch to __start_initialization_multiplatform using its address. Secondly, v9 and 10 specify branch targets as .+<offset>, so we convert those to actual addresses. Thirdly, v10 and 11 error out on a vmlinux if given the -R option complaining that it is "not a dynamic object". The -R does not make any difference to the asm output, so remove it. Lastly, v11 produces asm that is very similar to Gnu objtool (at least as far as branches are concerned), so no further changes are necessary to make it work.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
