    MIPS: perf: More robustly probe for the presence of per-tc counters · 800fb712
    Matt Redfearn authored
    The presence of per TC performance counters is now detected by
    cpu-probe.c and indicated by MIPS_CPU_MT_PER_TC_PERF_COUNTERS in
    cpu_data. Switch detection of the feature to use this new flag rather
    than blindly testing the implementation specific config7 register with a
    magic number.
