x86, UV: Initialize BAU MMRs only on hubs with cpus Remove the initialization of MMRs UVH_LB_BAU_SB_ACTIVATION_CONTROL and UVH_BAU_DATA_BROADCAST on UV hubs that have no active cpus. Such initialization on hubs with no active cpus would result in a kernel page fault. This is not of real high priority, because we don't have any such systems (with UV hubs that have no active cpus). But they will be coming. Signed-off-by: Cliff Wickman <cpw@sgi.com> LKML-Reference: <E1OZmZN-0006cW-RC@eag09.americas.sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
