I guess what I was trying to make sure I understood correctly is: if cache
has a matching VA, but MMU has no valid mapping, and our trap handling will
not add one - how does the cache compare PA?

Since this all happens in parallel, I guess the mmu fault trap will happen,
and we will not retry the instruction, but send a sigsegv to the process.
