* commit 'origin/master':
  suppress "pass-2 failed" messages from "stap -l FOOBAR"; just produce empty output
  make the mod_cu_function_cache a hash_map instead of map for more go-go
  PR5643: function caching for much faster syscall.* pass-2 processing
  Fixed PR 6499 (utrace probe crash).
  note "make installcheck" in post-build checkout
  Ignores signals when removing the temporary directory.
