commit 753ee9aee498bc8bf979fdb0b9272e7f4d1e3bb9
Author: Justus Winter <address@hidden>

    hurd: add proc_{get,set}_code
    
    Add routines to set and query the processes start_code and end_code
    locations. Any executable segments loaded from the ELF binary are in
    this range.
    
    * hurd/process.defs: Add proc_{get,set}_code.
    * hurd/process_reply.defs: Add proc_{get,set}_code.
    * hurd/process_request.defs: Add proc_{get,set}_code_request.
