            Bug ID: 193961
           Summary: [exp-run] Remove MAP_RENAME and MAP_NORESERVE
           Product: Ports Tree
           Version: Latest
          Hardware: Any
               URL: https://reviews.freebsd.org/D848
                OS: Any
            Status: Needs Triage
          Severity: Affects Only Me
          Priority: ---
         Component: Individual Port(s)
          Assignee: freebsd-ports-bugs@FreeBSD.org
          Reporter: jhb@FreeBSD.org

FreeBSD has never implemented these flags for mmap() and software that uses
them expecting Sun behavior is likely to be surprised.  From my recent mmap
error checking changes in HEAD, I know that at least openjdk7 and chromium both
use MAP_NORESERVE.  I'm not sure if either will gracefully handle the flag not
being defined or if they will need patching.  (I believe avg@ suggested openjdk
probably does not and will need patching.)

The patch can be found at the associated URL.
