We are going to switch core MM to 5-level paging abstraction. This is preparation step which adds <asm-generic/5level-fixup.h> As with 4level-fixup.h, the new header allows quickly make all architectures compatible with 5-level paging in core MM. In long run we would like to switch architectures to properly folded p4d level by using <asm-generic/pgtable-nop4d.h>, but it requires more changes to arch-specific code. Signed-off-by: Kirill A.

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.
