Merge tag 'v7m-next' of git://git.pengutronix.de/git/ukl/linux into devel-testing
Two bugfixes and trivial suspend support for v7m.
Given that the bugfixes are only relevant when an oops is in progress
and admitting that there are not so many v7m users I don't see an urge
to include the bugfixes in 3.14 and so target 3.15-rc1 for this pull
request.
