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
