powerpc: purge all the prefetched instructions for the coherent icache flush As Benjamin Herrenschmidt has indicated, we still need a dummy icbi to purge all the prefetched instructions from the ifetch buffers for the snooping icache. We also need a sync before the icbi to order the actual stores to memory that might have modified instructions with the icbi.
