Implement the architecture specific cache maintence functions that make up the "PMEM API". Currently the writeback and invalidate functions are the same since the function of the DCBST (data cache block store) instruction is typically interpreted as "writeback to the point of coherency" rather than to memory. As a result implementing the API requires a full cache flush rather than just a cache write back. This will probably change in the not-too-distant future.
