 ---------------------------
 
-What:  io_remap_page_range() (macro or function)
-When:  September 2005
-Why:   Replaced by io_remap_pfn_range() which allows more memory space
-       addressabilty (by using a pfn) and supports sparc & sparc64
-       iospace as part of the pfn.
-Who:   Randy Dunlap <rddunlap@osdl.org>

 What:  RAW driver (CONFIG_RAW_DRIVER)
 When:  December 2005
 Why:   declared obsolete since kernel 2.6.3
