Currently one resolves the location of the reserved_ttbr0 for PAN by taking a positive offset from swapper_pg_dir. In a future patch we wish to extend the swapper s.t. its size is determined at link time rather than comile time, rendering SWAPPER_DIR_SIZE unsuitable for such a low level calculation. In this patch we re-arrange the order of the linker script s.t. instead one computes reserved_ttbr0 by subtracting RESERVED_TTBR0_SIZE from swapper_pg_dir.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
