I merged in the flush_data_cache_page routine (from linux-
tag) instead of the ones from the mailing list and it's good as well.

Even though local_flush_data_cache_page is only used in
__ide_flush_dcache_range() (and that is inside a cpu_has_dc_aliases
check) it still might be good to fill it out anyway.
