In the anonymous page case, flush_anon_page() is always called prior to

Well, currently, we clear PG_arch_1 in flush_dcache_page(), at least on
ppc.
Now, I have a nagging feeling that we might not need to... Ill have to
give it a closer look when Im back from this extended week-end :-)
Cheers,
Ben.
