Subject[PATCH] feature removal of io_remap_page_range()
From: Randy Dunlap <rdunlap@xenotime.net>

As written in Documentation/feature-removal-schedule.txt,
remove the io_remap_page_range() kernel API.

This leaves one remaining caller at
arch/xtensa/kernel/pci.c:405:
and the xtensa maintainer (Chris Zankel) has committed to
sending a patch to convert this call this week.

Signed-off-by: Randy Dunlap <rdunlap@xenotime.net>

-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.
