+  void flush_anon_page(struct page *page, unsigned long vmaddr)
+       When the kernel needs to access the contents of an anonymous
+       page, it calls this function (currently only
+       get_user_pages()).  Note: flush_dcache_page() deliberately
+       doesn't work for an anonymous page.  The default
+       implementation is a nop (and should remain so for all coherent
+       architectures).  For incoherent architectures, it should flush
+       the cache of the page at vmaddr in the current user process.

+  void flush_kernel_dcache_page(struct page *page)
+       When the kernel needs to modify a user page is has obtained
+       with kmap, it calls this function after all modifications are
+       complete (but before kunmapping it) to bring the underlying
+       page up to date.  It is assumed here that the user has no
+       incoherent cached copies (i.e. the original page was obtained
+       from a mechanism like get_user_pages()).  The default
+       implementation is a nop and should remain so on all coherent
+       architectures.  On incoherent architectures, this should flush
+       the kernel cache for page (using page_address(page)).

   void flush_icache_range(unsigned long start, unsigned long end)
        When the kernel stores into addresses that it will execute
        out of (eg when loading modules), this function is called.
