When SEV is active, the second kernel image is loaded into encrypted memory. For that, make sure that when kexec builds the identity mapping page table, the memory is encrypted (i.e., _PAGE_ENC is set). [ bp: Sort local args and OR in _PAGE_ENC for more clarity. ] Co-developed-by: Brijesh Singh <brijesh.singh@amd.com> Signed-off-by: Brijesh Singh <brijesh.singh@amd.com> Signed-off-by: Lianbo Jiang <lijiang@redhat.com> Signed-off-by: Borislav Petkov <bp@suse.de> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: bhe@redhat.com Cc: dyoung@redhat.com Cc: "H.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
