This implements deferred IO support in fbdev. Deferred IO is a way to delay and repurpose IO. This implementation is done using mm's page_mkwrite and page_mkclean hooks in order to detect, delay and then rewrite IO. This functionality is used by hecubafb. [adaplas] This is useful for graphics hardware with no directly addressable/mappable framebuffer. Implementing this will allow the "framebuffer" to be accesible from user space via mmap().
