We want to be able to log the module name in early error messages, such as when module signature verification fails. Previously, the module name is set in layout_and_allocate(), meaning that any error messages that happen before (such as those in module_sig_check()) won't be logged with a module name, which isn't terribly helpful. In order to do this, reshuffle the order in load_module() and set up load info earlier so that we can log the module name along with these error messages. This requires splitting rewrite_section_headers() out of setup_load_info(). While we're at it, clean up and split up the operations done in layout_and_allocate(), setup_load_info(), and rewrite_section_headers() more cleanly so these functions only perform what their names suggest.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
