Not really.  This fixes that specific case but it doesn't fix the 
general case where a hardware device needs to call do_unassigned_access 
because the hardware device still only has the offset. 

You could store the physical base in each hardware device and recreate 
the physical address but that requires changing all hardware devices 
that need to do that.  Why should the hardware drivers go through the 
trouble to recreate a physical address when just a few instructions 
before then the physical address was known but irreversibly destroyed 
when it was converted to an offset.
