Fix a hard-coded limit of a maximum of 16 cpu's per socket. The UV Broadcast Assist Unit code initializes by scanning the cpu topology of the system and assigning a master cpu for each socket and UV hub. That scan had an assumption of a limit of 16 cpus per socket. With Westmere we are going over that limit. The UV hub hardware will allow up to 32. If the scan finds the system has gone over that limit it returns an error and we print a warning and fall back to doing TLB shootdowns without the BAU.
