Right now, if drivers or other code want to change, say, a cache attribute of a page, the only API they have is change_page_attr(). c-p-a is a really bad API for this, because it forces the caller to know *ALL* the attributes he wants for the page, not just the 1 thing he wants to change. So code that wants to set a page uncachable, needs to be aware of the NX status as well etc etc etc. This patch introduces a set of new APIs for this, set_pages_<attr> and set_memory_<attr>, that offer a logical change to the user, and leave all attributes not implied by the requested logical change alone.
