[PATCH] m68k: move cache functions into separate file
Move a few cache functions into its own file and fix flush_icache_range() so it can handle both kernel and user addresses correctly (assuming context is set correctly). Turn copy_to_user_page/copy_from_user_page into inline functions and add a missing cache flush.
