a fallback during cpuid helpers reorg - Initialize reserved fields in the SVSM page validation calls structure to zero in order to allow for future structure extensions - Have the sev-guest driver's buffers used in encryption operations be in linear mapping space as the encryption operation can be offloaded to an accelerator - Have a read-only MSR write when in an AMD SNP guest trap to the hypervisor as it is usually done. This makes the guest user experience better by simply raising a #GP instead of terminating said guest - Do not output AVX512 elapsed time for kernel threads because the data is wrong and fix a NULL pointer dereferencing in the process - Adjust the SRSO mitigation selection to the new attack vectors -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEzv7L6UO9uDPlPSfHEsHwGGHeVUoFAmihmPcACgkQEsHwGGHe VUr6Iw/+KKuQdicPRvdQ8Kv+710oHFHka1CY/LdHuADuuzWWE+Zj6RzwraM0aqIr 1E4resu05MPVJj3KAzt0rBS4Ch5bbNU0QHQqhuuxe+EZpbY8XNxx53f43E4wHTS8 bPaZI1GdLZSTh5BUGRj9N0udK5gnd6kbku80PAbP2fqi+aSOZSA8JCqmiUicSi0/ EbYye7n38q8u1Dh2y9t9CBuxAOZEyzCM6LXRELmK5lya1LGJkKOTGllyb8irzsiv HlLW1sN+weeVlvdUd1LvaYgTAetNhSVtiuh71cGMENnpoAyO6HAea+7X8Tg7UHHp zsYRVXKg2CENQpo4OsQ3q/O7fnPTets7NFm8DNwSKO0qoCqn3Yf4AD4IeCIqZdM3 B2an4b1SWN2xtW38YEEGFVKIBIZVLQFzjmwR3yu8wqjhycIW3rNRCiQuI4EvW+ej kx5ZXHXHKvThoLuxio/ILce1oWa4O9K+GzV9vEDHtYK283sCUU2XyUOVq3Ntpmoc /mzOaBWAjN9nMWJ01DoPRh0bs5nkbN/NQxIOHUiOtLmMkwJX9ls/ed2VagL/iMq1 Sj1RZqkLEUYSHgE+HOToK8LXhbuDp6QEv1FUL/29pu1fzXRn5cn0PJx56+EKjJWO f7b3NWMNGbbD/sIcYAtU73GVNnAOGzUkNA7AjDfmq+YoiC5G+LA= =zsPJ -----END PGP SIGNATURE----- Merge tag 'x86_urgent_for_v6.17_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fixes from Borislav Petkov: - Remove a transitional asm/cpuid.h header which was added only as a fallback during cpuid helpers reorg - Initialize reserved fields in the SVSM page validation calls structure to zero in order to allow for future structure extensions - Have the sev-guest driver's buffers used in encryption operations be in linear mapping space as the encryption operation can be offloaded to an accelerator - Have a read-only MSR write when in an AMD SNP guest trap to the hypervisor as it is usually done.
