If I build for the m5475evb defconfig then I get warnings like this:

Thanks, I did some m68knommu compile tests, but didn't see this warning, which
happens for Coldfire+MMU only.
The issue is that there are two ways to declare an architecture has
ioremap_wt():
1. By defining ioremap_wt,
2. By defining ARCH_HAS_IOREMAP_WT.
1 is done in arch/m68k/include/asm/kmap.h.
2 is done in arch/m68k/include/asm/io_mm.h. Moving that to kmap.h fixes
the warning. Will send an update shortly.
