From: Joerg Roedel <jroedel@xxxxxxx> Hi, two small patches to disable kexec on x86 when running as an SEV-ES guest. Trying to kexec a new kernel would fail anyway because there is no mechanism yet to hand over the APs from the old to the new kernel. Supporting this needs changes in the Hypervisor and the guest kernel as well. This code is currently being work on, but disable kexec in SEV-ES guests until it is ready. Please review.
