Ah, of course. This is ident map so by definition it cannot map phys
addresses above 4G. And since __virt_to_phys() suppose to work only on
ident map it's OK to returns unsigned long.
Let's get this right... the lack of correct

Offer a method to drop this identity mapping through

Make all the above depend on CONFIG_ARM_VIRT_EXT and CONFIG_ARM_LPAE.
