    s390/smp: cleanup core vs. cpu in the SCLP interface · d08d9430
    Martin Schwidefsky authored
    The SCLP interface to query, configure and deconfigure CPUs actually
    operates on cores. For a machine without the multi-threading faciltiy
    a CPU and a core are equivalent but starting with System z13 a core
    can have multiple hardware threads, also referred to as logical CPUs.
    
    To avoid confusion replace the word 'cpu' with 'core' in the SCLP
    interface. Also replace MAX_CPU_ADDRESS with SCLP_MAX_CORES.
    The core-id is an 8-bit field, the maximum thread id is in the range
    0-31. The theoretical limit for the CPU address is therefore 8191.
