Hi,

I am resending my patches, differrences from previous send:
* fixed some style issues
* introduce seq_print_user_ip helper
* make mangle_path global and document
* use mangle_path instead of abusing seq_file in trace_seq_path
* fix subject line and commit messages

These patches apply on top of tip/master,
commit 50598e26c1360d4c0edcabc50035d084ee8d3d70

Török Edwin (2):
  tracing: add support for userspace stacktraces in tracing/iter_ctrl
  tracing: identify which executable object the userspace address
    belongs to
