New Revision: 308820
URL: https://svnweb.freebsd.org/changeset/base/308820
Log:
Report page faults due to reserved bits in PTEs as a separate fault type.
Rather than reporting a page fault due to a bad PTE as a protection
violation with the "rsv" flag, treat these faults as a separate type of
fault altogether.
