commit fa696039448ed6a6f72c6ecac8e7e664820cbf6e
Author: David Smith <dsmith@redhat.com>
Date:   Fri Sep 7 14:57:18 2012 -0500

    (PR14488 partial fix) Make memory reading more robust.
    
    * runtime/dyninst/runtime.h (assert_is_myproc): New dummy macro.
      (stp_dummy_init): Opens the /proc/self/mem file.
      (stp_dummy_exit): Close the file.
    * runtime/dyninst/linux_defs.h (user_mode): New dummy macro.
      (__copy_from_user): Rewrote to read memory from /proc/self/mem, to be
      able to catch errors.
    * runtime/stp_string.h (__stp_get_user): Always use __get_user(), no
      matter what arch we're on in dyninst mode.
    * tapset/uconversions.stp: Moved from tapset/linux/uconversions.stp, since
      the dyninst runtime can use the functions also.
