This is a preparatory rework to allow uncoupling virtual and physical addresses spaces. Currently __kaslr_offset is the kernel offset in both physical memory on boot and in virtual memory after DAT mode is enabled. Uncouple these offsets and rename the physical address space variant to __kaslr_offset_phys while keep the name __kaslr_offset for the offset in virtual address space. Do not use __kaslr_offset_phys after DAT mode is enabled just yet, but still make it a persistent boot variable for later use. Use __kaslr_offset and __kaslr_offset_phys offsets in proper contexts and alter handle_relocs() function to distinguish between the two.

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 reStructuredText 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.
