    Here a STFLE result on a EC12 GA2, already more than 128 bits... Is that model on the list?

    [mimu@p57lp59 s390xfac]$ ./s390xfac -b
    fac[0] = 0xfbfffffbfcfff840
    fac[1] = 0xffde000000000000
    fac[2] = 0x1800000000000000

    The architecture at least defines more than 2 or 3. Do you want me to limit it to an arbitrary
    size?. Only in QEMU or also in the KVM interface?

    Thanks
