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.
