  * __boot_cpu_mode records what mode CPUs were booted in.
  * A correctly-implemented bootloader must start all CPUs in the same mode:
  * In this case, both 32bit halves of __boot_cpu_mode will contain the

  * Should the bootloader fail to do this, the two values will be different.
  * This allows the kernel to flag an error when the secondaries have come up.
