[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.
