commit b100897fdb986b1338099351e6b60a187572ce47
Author: Mark Wielaard <mjw@redhat.com>
Date:   Fri Oct 21 13:34:21 2011 +0200

    Extend vma_map entry vm_end range when additional segments are mapped.
    
    Once registered, we may want to extend an earlier registered region.
    A segment might be mapped with different flags for different offsets.
    If so we want to record the extended range so we can address more
    precisely to module names and symbols.
    
    * runtime/task_finder_vma.c (__stp_tf_get_vma_map_entry_end_internal):
      New function.
      (stap_extend_vma_map_info): Likewise.
    * runtime/vma.c (_stp_vma_mmap_cb): Call stap_extend_vma_map_info().
