When we are mapping the initial sections in head.S we know very well where the start and end of the kernel image in physical memory is placed. Later on it gets hard to determine this. Save the information into two variables named kernel_sec_start and kernel_sec_end for convenience for later work involving the physical start and end of the kernel. These variables are section-aligned corresponding to the early section mappings set up in head.S.

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.
