 * CPU-specific target implementation
 *
 * Each CPU provides a set of debugging facilities.  We have per-CPU "modules",
 * each of which exposes a kmt_cpu_t.  When initialized, these modules will
 * install dcmds, walkers, and the like in order to allow the user to take
 * advantage of features specific to the CPU being used.
