I do not see any users, neither upstream nor in Avi's tree.
There aren't.
To my (semi-)understanding, offset should correlate to region_offset of
cpu_register_physical_memory_offset: legacy device models require this
to be 0 as they expect an absolute memory address passed to their
handler, in contrast to a normal one that is relative to the regions
base. But I do not see how the memory region offset actually helps here.
mr->offset is added to the address in memory_region_{read,write}_thunk_n().
