[PATCH 0/3] Volatile Ranges

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

So the last RFC iteration of this patch set didn't get any feedback,
so I wanted to properly submit the volatile range functionality for
inclusion.  I suspect this will bring some useful critiques out of
the wood work, which I'd welcome, but maybe not and this can be
queued. Here's to optimism. :)

In addition to the two patches for volatile ranges, I've also
included an RFC patch converting the ashmem driver to use volatile
ranges.

Thoughts or feedback on it would be appreciated.

thanks
