That happens because we pass the uninitialized gisa\norigin to virt_to_phys() before writing it to the gisa designation.\n\nTo fix this we return 0 in kvm_s390_get_gisa_desc() if the origin is 0.\nkvm_s390_get_gisa_desc() is used to determine which gisa designation to\nset in the SIE control block. A value of 0 in the gisa designation disables\ngisa usage.\n\nThe issue surfaces in the host kernel with the following kernel message as\nsoon a new kvm guest start is attemted.\n\nkvm: unhandled
