For the most part this consists of fleshing out the MMU and cache handling, it doesn't add pmap optimizations possible with these CPU, yet, though. With these changes FreeBSD runs stable on Fujitsu Siemens PRIMEPOWER 250 and likely also other models based on SPARC64 V like 450, 650 and 850. Thanks go to Michael Moll for providing access to a PRIMEPOWER 250.
