The v3 is just a rearranged v2 so as to move the post sensitive patch (previous patch 2)
to the end of the series.   [After applying the full series the code is the same as before.]

For easier testing, the series (along with some previous patches depended on by it)
is available in the pm-s2idle-testing branch of the linux-pm.git tree at kernel.org:

https://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git/log/?h=pm-s2idle-testing

Please refer to the changelogs for details.

Thanks,
Rafael
