Yes all kernel domain read would use that address range.  In the end
it is only the vm_insert_pfn() call that needs the physical.

I thought about that.  I don't think it's worth it.  Point() does it's
job fine.  I could add a peer to point called physaddr() that returns
an address instead of a pointer.  That really doesn't doesn't help me.
 I named it mtd_get_partition_physaddr() because all I need is to get
the physical address of the mtd partition.  And if I get around to
doing an acceptable port of XIP cramfs thats all it would need too.
