+ * This function is to be used for kernel mapping of buffer objects.
+ * It chooses the appropriate mapping method depending on the memory type
+ * and caching policy the buffer currently has.
+ * Mapping multiple pages or buffers that live in io memory is a bit slow and
+ * consumes vmalloc space. Be restrictive with such mappings.
+ * Mapping single pages usually returns the logical kernel address, (which is fast)
+ * BUG may use slower temporary mappings for high memory pages or
+ * uncached / write-combined pages.
+ *
+ * The function fills in a drm_bo_kmap_obj which can be used to return the
+ * kernel virtual address of the buffer.
+ *
+ * Code servicing a non-priviliged user request is only allowed to map one
+ * page at a time. We might need to implement a better scheme to stop such
+ * processes from consuming all vmalloc space.
