commit 2b5d00b6c2cdd94f6d6a494a6f6c0c0fc7b8e711 upstream. In preparation for encrypting more than just the kernel during early boot processing, centralize the use of the PMD flag settings based on the type of mapping desired. When 4KB aligned encryption is added, this will allow either PTE flags or large page PMD flags to be used without requiring the caller to adjust.

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.
