    Subject[PATCH v4 00/12] perf metric fixes and test
    From
    Add a test that all perf metrics (for your architecture) are parsable
    with the simple expression parser. Attempt to parse all events in
    metrics but only fail if the metric is for the current CPU. Fix bugs
    in the expr parser, x86 and powerpc metrics. Improve debug messages
    around add PMU config term failures.

    v4 rebases after Kajol Jain's patches and fixes an asprintf warning.
    v3 adds parse event testing of ids and improves debug messages for add
    PMU. These messages are paticular visible with 'perf test 10
    -vvv'. It moves the testing logic from tests/expr.c to
    tests/pmu-events.c as suggested by John Garry
    <john.garry@huawei.com>.
    v2 adds Fixes tags to commit messages for when broken metrics were
    first added. Adds a debug warning for division by zero in expr, and
    adds a workaround for id values in the expr test necessary for
    powerpc. It also fixes broken power8 and power9 metrics.

    Ian Rogers (12):
    perf expr: unlimited escaped characters in a symbol
    perf metrics: fix parse errors in cascade lake metrics
    perf metrics: fix parse errors in skylake metrics
    perf expr: allow ',' to be an other token
    perf expr: increase max other
    perf expr: parse numbers as doubles
    perf expr: debug lex if debugging yacc
    perf metrics: fix parse errors in power8 metrics
    perf metrics: fix parse errors in power9 metrics
    perf expr: print a debug message for division by zero
    perf parse-events: expand add PMU error/verbose messages
    perf test: improve pmu event metric testing
