    signalfd4, rt_tgsigqueueinfo
  arm: added architecture-specific implementation of __cr_restore_rt

Andrey Vagin (12):
  zdtm: add a test case for pending signals
  protobuf: add a new description for saving siginfo-s
  crtools: add a callback to show signal=*.img
  crtools: add image contants for pending signals (v2)
  crtools: dump pending signals (v4)

  check: check PTRACE_PEEKSIGINFO and sigqueueinfo with positive
    si_code (v2)
  crtools: remove declaration of rt_sigset_t
  restore: set up correct sa_restorer for SIGCHLD handler (v3)
