    Subject[PATCH 33/57] perf c2c report: Add pid sort key
    Date
    Adding pid dimension key wrapper.

    It is to be displayed in the single cacheline output:

    pid

    We currently don't have a single 'pid' sort/display entry,
    which would output just pid number, hence adding it into
    c2c code.
