This patchset doesn't works for physical address monitoring because I forgot
below patch.  Sorry for missing it.  Please apply it before you test this
patchset.  Or, you can clone the patch applied complete git tree:

    $ git clone git://github.com/sjp38/linux -b cdamon/rfc/v6.1

The web is also available:
https://github.com/sjp38/linux/releases/tag/cdamon/rfc/v6.1

The patch will be split and squashed in appropriate patch in the next spin.
