Instead of using constant addresses for the normal and dump-info stacks, allocate both stacks in the decompressor's image and load the stack register in a position-independent manner. This will allow loading and entering the decompressor at an arbitrary memory address without corrupting the content at the fixed addresses used until now for both stacks. This is one of the prerequisites for being able to kexec the decompressor from its load address without relocating it first.

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.
