An undocumented and indeed unmentioned feature of patch 2 is that
UINT64_MAX sizes are expanded to UINT64_MAX+1.  I did that to avoid
introducing memory_region_init_128() (or perhaps
memory_region_init_2_64() that doesn't take a size argument).  That
removes the ability to create container regions that span exactly
UINT64_MAX bytes.  It is strange in a patchset that tries to makes
things more regular, I admit.
