    perf c2c report: Display node for cacheline address · 7f834c2e
    Jiri Olsa 提交于
    Adding the NUMA node info for the data cacheline. Adding the new column
    to both "Shared Data Cache Line Table" and "Shared Cache Line
    Distribution Pareto".
    
    Note the new 'Node' column next to the 'Cacheline'.
