Right, and I think the fix is as simple as this because we don't care about kaiser in the bootstrap kernel:
--- diff --git a/arch/x86/boot/compressed/pagetable.c b/arch/x86/boot/compressed/pagetable.c index d5364ca2e3f9..63eaa71ad9f1 100644 --- a/arch/x86/boot/compressed/pagetable.c +++ b/arch/x86/boot/compressed/pagetable.c @@ -22,6 +22,7 @@ * the SME support to avoid any compile and link errors. */ #undef CONFIG_AMD_MEM_ENCRYPT +#undef CONFIG_KAISER #include "misc.h"
-- Regards/Gruss, Boris.
