    Subject[PATCH 00/15] Android ETM driver changes
    Since I didn't hear any objections to the earlier RFC release
    last week, I wanted to send this on for inclusion.

    The Android kernel tree has a number of changes to the ETM driver.
    Arve sent the first 9 of these to the list over a year ago and
    got very little response.

    I didn't want these to get lost, so I pinged Alexander about
    these privately and he stated that he wasn't actively
    maintaining the driver, but after skimming the entire set he
    acked the series and suggested I send it on to Russel for
    review and inclusion.
