The decompressor can load from anywhere in memory, and the only reason the EFI stub code relocates it is to ensure it appears within the first 128 MiB of memory, so that the uncompressed kernel ends up at the right offset in memory. We can short circuit this, and simply jump into the decompressor startup code at the point where it knows where the base of memory lives. This also means there is no need to disable the MMU and caches, create new page tables and re-enable them.

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.
