This is why I've been advocating for the index-based definition of ptrtoaddr. So there's no need to do this 48-bit thing on the assumption that the base of a buffer fat pointer is "aligned enough" (in most contrxts where I've seen this the start point is some sort of allocation that'll definitely be align(16) or better)
