Joerg Roedel c9f09539e1 x86/head/64: Check SEV encryption before switching to kernel page-table ... When SEV is enabled, the kernel requests the C-bit position again from the hypervisor to build its own page-table. Since the hypervisor is an untrusted source, the C-bit position needs to be verified before the kernel page-table is used. Call sev_verify_cbit() before writing the CR3.
