Tom Lendacky 7f8b7e7f4c x86/mm: Add support for early encryption/decryption of memory
Add support to be able to either encrypt or decrypt data in place during
the early stages of booting the kernel. This does not change the memory
encryption attribute - it is used for ensuring that data present in either
an encrypted or decrypted memory area is in the proper state (for example
the initrd will have been loaded by the boot loader and will not be
encrypted, but the memory that it resides in is marked as encrypted).
