From: Michael Cree <mcree@orcon.net.nz>
3.4.104-rc1 review patch. If anyone has any objections, please let me know.
------------------
commit 25534eb7707821b796fd84f7115367e02f36aa60 upstream.
These functions are used in some PCI drivers with big-endian MMIO space.
Admittedly it is almost certain that no one this side of the Moon would use such a card in an Alpha but it does get us closer to being able to build allyesconfig or allmodconfig, and it enables the Debian default generic config to build.
