Linus Torvalds 408323581b - Add support for running the kernel in a SEV-SNP guest, over a Secure ... VM Service Module (SVSM). When running over a SVSM, different services can run at different protection levels, apart from the guest OS but still within the secure SNP environment. They can provide services to the guest, like a vTPM, for example. This series adds the required facilities to interface with such a SVSM module. - The usual fixlets, refactoring and cleanups -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEzv7L6UO9uDPlPSfHEsHwGGHeVUoFAmaWQuoACgkQEsHwGGHe VUrmEw/+KqM5DK5cfpue3gn0RfH6OYUoFxOdYhGkG53qUMc3c3ka5zPVqLoHPkzp WPXha0Z5pVdrcD9mKtVUW9RIuLjInCM/mnoNc3tIUL+09xxemAjyG1+O+4kodiU7 sZ5+HuKUM2ihoC4Rrm+ApRrZfH4+WcgQNvFky77iObWVBo4yIscS7Pet/MYFvuuz zNaGp2SGGExDeoX/pMQNI3S9FKYD26HR17AUI3DHpS0teUl2npVi4xDjFVYZh0dQ yAhTKbSX3Q6ekDDkvAQUbxvWTJw9qoIsvLO9dvZdx6SSWmzF9IbuECpQKGQwYcp+ pVtcHb+3MwfB+nh5/fHyssRTOZp1UuI5GcmLHIQhmhQwCqPgzDH6te4Ud1ovkxOu 3GoBre7KydnQIyv12I+56/ZxyPbjHWmn8Fg106nAwGTdGbBJhfcVYfPmPvwpI4ib nXpjypvM8FkLzLAzDK6GE9QiXqJJlxOn7t66JiH/FkXR4gnY3eI8JLMfnm5blAb+ 97LC7oyeqtstWth9/4tpCILgPR2tirrMQGjUXttgt+2VMzqnEamnFozsKvR95xok 4j6ulKglZjdpn0ixHb2vAzAcOJvD7NP147jtCmXH7M6/f9H1Lih3MKdxX98MVhWB wSp16udXHzu5lF45J0BJG8uejSgBI2y51jc92HLX7kRULOGyaEo= =u15r -----END PGP SIGNATURE----- Merge tag 'x86_sev_for_v6.11_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 SEV updates from Borislav Petkov: - Add support for running the kernel in a SEV-SNP guest, over a Secure VM Service Module (SVSM).
