The SRCU for modules optimization (commit title "srcu: Allocate per-CPU data for DEFINE_SRCU() in modules") introduced vmlinux linker entries which is unused since it applies only to the built-in vmlinux. So remove it to prevent any space usage due to the 8 byte alignment it added. vmlinux.lds.h has no effect on module loading and is not used for building the module object, so the changes were not needed in the first place since the optimization is specific to modules. Tested with SRCU torture_type and rcutorture. Put prints in module loader to confirm it is able to find and initialize the srcu structures.

README
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.
