What if the failure doesn't happen? Say, someone mmap()ed over the page.
Sorry, not get your idea clearly. hva is re-mmap()ed? We just read the
hva, not write, so I think it should be OK here.
We don't generate a signal in this case. Does the code continue to work
correctly (not sure what correctly is in this case... should probably
just continue).
There's also the possibility of -EFAULT.
