 * To allow safe resume of do_memory_op() after preemption, we need to know

 * high-order bits of the @cmd parameter, which are otherwise unused and zero.

 *

 * Note that both of these values are effectively part of the ABI, even if

 * we don't need to make them a formal part of it: A guest suspended for

 * migration in the middle of a continuation would fail to work if resumed on

 * a hypervisor using different values.
