commit bcc1790f75ce55fc27666f250c98e2522536d54f
Author: David Smith <dsmith@redhat.com>
Date:   Wed Oct 12 16:52:30 2011 -0500

    Fixed PR12389 by making %m/%M use kread() to access memory.
    
    * runtime/vsprintf.c (_stp_vsprint_memory): The '%m' and '%M' formatting
      operators use kread() to read memory.
    * translate.cxx: Removed all support from the c_unparser class for
      'probe_or_function_needs_deref_fault_handler' processing since it is no
      longer needed.
      (c_unparser::visit_print_format): Removed deref_buffer() call.  Added
      check for c->last_error after print is done.
    * runtime/runtime_context.h: New file.
    * runtime/vsprintf.h: Ditto.
    * runtime/print.c: Removed extra include of vsprintf.c.  Allow use to
      override STP_LOG_BUF_LEN.  Make _stp_print_flush() definitions exactly
      the same between the RELAY_{GUEST,HOST} and normal caes.
    * runtime/print.h: Added a few more functions and includes the new
      vsprintf.h file.
    * runtime/runtime.h: Includes print.h instead of print.c.  Moved print.c
      and io.c to runtime_context.h.
    * runtime/transport/transport.h: Declares '_stp_target'.
