BTW do you need swiotlb_bus_to_virt to be __weak or is the fact that  
it
is implemented in terms of swiotlb_bus_to_phys sufficient?

The default one in swiotlb calls phys_to_virt on the result of  
swiotlb_bus_to_phys, which only works on lowmem.

Perhaps we can simply enhance the default one to handle highmem instead
of making it arch specific?
