These are all the same as the default from asm-generic.h.  Do we really
need these definitions in alpha, avr32, frv, ia64, x86?

Those arches do not include asm-generic.h (I suppose for a good reason)

OK, that explains it.  I'm not at all sure there's a good reason for
those arches not using asm-generic.h, but I haven't looked at the code
to see.

but a definition is needed anyway if we want code using ioremap_nopost()
to be unconditional. This is one way of doing it, there are others not
sure they are any better, I am open to suggestions.
