Now that the build has finished... even with that fixed...

arch/arm/mach-versatile/built-in.o: In function `pci_versatile_setup':
arch/arm/mach-versatile/pci.c:249: undefined reference to `pci_ioremap_io'
kernel/built-in.o: In function `set_section_ro_nx':
kernel/module.c:1738: undefined reference to `set_memory_nx'
kernel/built-in.o: In function `set_page_attributes':
kernel/module.c:1709: undefined reference to `set_memory_ro'

which means that DEBUG_SET_MODULE_RONX also needs to depend on MMU.
As for the pci_ioremap_io, I'm not sure what to do about that.

In any case, I'll queue up both of these dependency fixes as low
priority.  Thanks.
