[edk2-devel] [PATCH] UefiCpuPkg: Store SEV-SNP AP jump table in the secrets page

A full-featured SEV-SNP guest will not rely on the AP jump table, and will instead use the AP Creation interface defined by the GHCB. However, a guest is still allowed to use the AP jump table if desired. However, unlike with SEV-ES guests, SEV-SNP guests should not store/retrieve the jump table
