[PATCH 00/15][RFC] Android ETM driver changes

[John Stultz <john.stultz@linaro.org>]

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
acked the series and suggested I send it on to Russel for
review and possible inclusion.

So here they are. Please let me know if there are any
objections to merging these, or if further changes are
needed.
