Alpha needs to have the system bus address for the device's local
memory available, so that it can be returned to user-level, where
it may be used in an mmap(). So, we make bus.addr hold the ioremap()
return for kernel use, and then we can modify bus.base appropriately.

Hi, Dave,
It is the explanation that is inaccurate; I was still thinking about mmap when
the new paradigm is to do the mapping when the VM faults.
I believe the code that requires this patch is: ttm/ttm_bo_vm.c:
ttm_bo_vm_fault(),
specifically:
for (i = 0; i < TTM_BO_VM_NUM_PREFAULT; ++i) {
