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.

thanks
-john
