    Subject[PATCH] perf tools: Revert the -Wswitch-enum flag
    Date
    -Wswitch-enum warns when a switch statement doesn't handle
    every enum values of a given type.

    But it also warns whn we have a default case where we handle them.
    This forces workarounds like having a rain of ignored enum values
    cases falling down to the default case.

    We want to be sure that every cases are handled (which is what does
    -Wswitch-default), but we don't want to explicitly write what must
    fall down to the default case.
