    qa: valgrind check /proc/{stat,interrupts,softirqs} use
    
    Add a test 857 to exercise more Linux kernel metrics using
    valgrind.  Resolve a few writes into uninitialised memory
    in the process - in particular, a long-standing issue in
    map_online_cpus() is now resolved, where "unsigned long"s
    were written into an "unsigned int" CPU ID array.
