Borislav Petkov 541ac97186 x86/sev: Make the #VC exception stacks part of the default stacks storage ... The size of the exception stacks was increased by the commit in Fixes, resulting in stack sizes greater than a page in size. The #VC exception handling was only mapping the first (bottom) page, resulting in an SEV-ES guest failing to boot. Make the #VC exception stacks part of the default exception stacks storage and allocate them with a CONFIG_AMD_MEM_ENCRYPT=y .config. Map them only when a SEV-ES guest has been detected. Rip out the custom VC stacks mapping and storage code.
