As a preparation for moving the .dma.data section from the decompressor to the decompressed kernel, the .dma.data section must be made relocatable by replacing absolute memory addressing with relative one. This is required in order to be able to relocate the DMA section to a memory address <= 2G as required by the hardware architecture. The DMA section must be relocated in case the decompressed kernel was loaded to an address >= 2G which can occur if KASAN is enabled. By making the whole DMA section position-independent we avoid applying relocations to it whenever it is moved to a different address, which becomes possible as soon as it becomes a part of the decompressed kernel.

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.
