The immovable memory ranges information in the SRAT table is necessary to fix the issue of KASLR not paying attention to movable memory regions when selecting the offset. Therefore, SRAT needs to be parsed. Depending on the boot: KEXEC/EFI/BIOS, the methods to compute RSDP are different. When booting from EFI, the EFI table points to the RSDP. So iterate over the EFI system tables in order to find the RSDP.

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.
