commit 18da588786c9d0e98f7cd79fbc5550cecee853e0
Author: Mark Wielaard <mjw@redhat.com>

    PR10080 Add vdso tracking (x86).
    
    The translator will now pick up all the possible vdso.so files (luckily
    they are small). At runtime when the task finder notifies us of a new
    process we will check against the build id an add the vdso to the vma map.
    
    * translate.cxx (find_vdso): New function.
      (add_unwindsym_vdso): Likewise.
      (emit_symbol_data): If vma tracker enabled call add_unwindsym_vdso.
    * buildrun.cxx (compile_pass): Check STAPCONF_MM_CONTEXT_VDSO.
    * runtime/autoconf-mm-context-vdso.c: New test.
    * runtime/vma.c (_stp_vma_match_vdso): New function.
      (_stp_vma_exec_cb): Call _stp_vma_match_vdso when register_p && process_p.

    * session.cxx (systemtap_session::systemtap_session): Remove symtab init.
