Tom Lendacky f88a68facd x86/mm: Extend early_memremap() support with additional attrs ... Add early_memremap() support to be able to specify encrypted and decrypted mappings with and without write-protection. The use of write-protection is necessary when encrypting data "in place". The write-protect attribute is considered cacheable for loads, but not stores. This implies that the hardware will never give the core a dirty line with this memtype.
