511 * consecutive value of the "-smp" maxcpus option.
512 *
513 * For small variations of the kind caused by different iasl versions,
514 * the 4k rounding usually leaves slack. However, there could be still
515 * one or two values that break. For QEMU 1.7 and QEMU 2.0 the
516 * slack is only ~10 bytes before one "-smp maxcpus" value breaks!

519 * QEMU 1.7 it is 6414. For RHEL/CentOS 7.0 it is 6418.
