commit eb032788e69844946b62c75ab6389ae937b711f6
Author: David Smith <dsmith@redhat.com>
Date:   Thu Oct 27 11:09:05 2011 -0500

    Avoid "sleeping function called from invalid context" kernel errors.
    
    * runtime/stp_utrace.c (utrace_task_alloc): Change memory allocation flags
      to avoid waiting.
      (utrace_attach_task): Ditto.
      (finish_callback): Remove call to might_sleep(), since tracepoint
      handlers (and now utrace handlers) can't sleep.

commit 54e7e8f0122569091f780fc0f1acc1520b09f1c4
Author: David Smith <dsmith@redhat.com>
Date:   Thu Oct 27 11:06:14 2011 -0500

    More PR13083 fixes to avoid sleeping in the task_finder (ported).
    
    * runtime/task_finder2.c (__stp_get_mm_path): Call down_read_trylock()
      instead of down_read() to avoid the possibility of sleeping.
      (stap_start_task_finder): Call task_lock() to make sure a task's mm
      doesn't go away while we're looking at it.
