Hmm, seems like they do.

I'm confused.  What was the exact reason for having a separate
function for anon pages?  Wouldn't unifying the functionality of
flush_dcache_page() and flush_anon_page() make more sense?

Otherwise sparc and ppc would have to check PageAnon() from both
flush_dcache_page() and flush_anon_page() and call a common function,
which seems to just complicate things without any gain.
