Try ioremap_nocache()
That's just a front-end to __ioremap().  I'm trying to make REAL RAM as
uncacheable, not PCI memory.  ioremap() does not work on real RAM, only high
addresses outside of physical memory.
You could use ClearPageReserved() + ioremap(), but ioremap() is limited
to the first 4 GB.
