In 5.1 we "fixed" it by removing the nopage handler from privcmd; having VM_PFNMAP with a nopage handler just makes no sense. However, the problem with it is that if userland did something it wasn't supposed to, it would actually get a page full of zeros instead of a SIGBUS. In 5.2 I believe we have added a nopfn handler which returns SIGBUS if the userland program does the wrong thing.
