mainlining shenanigans

Stack protection is not compatible with early boot code. All of the early SME boot code is now isolated in a separate file, mem_encrypt_identity.c, so arch/x86/mm/Makefile can be updated to turn off stack protection for the entire file. This eliminates the need to worry about other functions within the file being instrumented with stack protection (as was seen when a newer version of GCC instrumented sme_encrypt_kernel() where an older version hadn't). It also allows removal of the __nostackprotector attribute from individual functions.

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.
