Patch from Ben Dooks Change the initialiser for the map_desc for the iPAQ RX3715 to use the new pfn initialiser, and also reduce the amount of ISA space mapped (we only need to stop any ISA IO writes OOPsing the system, so do not need >1Mbyte of space) Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
