    [SPARC32]: Rework the CPU enumeration and probing code · fb5ba71d
    Keith M. Wesolowski authored
    The low 2 bits of the MID are now used exclusively as the software
    CPU ID on 4m.  This eliminates entirely the need for mid_xlate.  We
    also eliminate linux_num_cpus and linux_cpus; since the hardware-based
    id is now used everywhere we don't need indexed CPU tables.
    
    The device probe is almost identical to sparc64's version.  The one
    exception is that 4m only uses the bottom 2 bits of the MID, so we also
    have a separate function to get the true hardware MID for the rare times
    it's actually needed.
    
    Per-cpu data is now used the same way as in sparc64.  As a side benefit
    we now display the same format Bogo and Clock values in /proc/cpuinfo.
