Log message:
add two new MD only pmap apis to amd64 and i386 (not to be used in MI
code):
pmap_flush_cache(vaddr_t, vsize_t) and pmap_flush_page(paddr_t) to flush
the cache for virtual addresses and physical pages respectively using
the clflush instruction. These apis will shortly be used by the agp
bus_dma functions to avoid doing a wbinvd on each dmamap_sync.
