Hi Yinghai, Hi All,

my current thinking with regards to this is that I would like to take
these changes into the kexec-tools tree once there is consensus and
kernel portions have been accepted. If that makes sense please let me know
when those conditions have been met. Otherwise lets discuss a different
strategy.
