New Revision: 349245
URL: https://svnweb.freebsd.org/changeset/base/349245

Log:
  Add PROT_MAX to the HISTORY section.
  
  In the case of mmap(), add a HISTORY section.  Mention that mmap() and
  mprotect()'s documentation predates an implementation.  The
  implementation first saw wide use in 4.3-Reno, but there seems to be no
  easy way to express that in mdoc so stick with 4.4BSD.
