    each core be created in the _cpu_init function
    call.  The cpufreq infrastructure doesn't call
    _cpu_init for the second core in each processor.
    Some systems crashed when _get was called with
    an odd-numbered core because it tried to
    dereference a NULL pointer since the data
    structure had not been created.
    
    The attached patch solves the problem by
    initializing data structures for all shared
    cores in the _cpu_init function.  It should
    apply to 2.6.12-rc6 and has been tested by
    AMD and Sun.
