Tom Lendacky b9d05200bc x86/mm: Insure that boot memory areas are mapped properly
The boot data and command line data are present in memory in a decrypted
state and are copied early in the boot process.  The early page fault
support will map these areas as encrypted, so before attempting to copy
them, add decrypted mappings so the data is accessed properly when copied.

For the initrd, encrypt this data in place. Since the future mapping of
the initrd area will be mapped as encrypted the data will be accessed
properly.

README

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.
