int pdc_mem_map_hpa (struct pdc_memory_map * address, struct pdc_module_path * mod_path);
This call was developed for S700 workstations to allow the kernel to find the I/O devices (Core I/O). In the future (Kittyhawk and beyond) this call will be replaced (on workstations) by the architected PDC_SYSTEM_MAP call.
This call is supported by all existing S700 workstations (up to Gecko).
