---------------------------
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
