I see this with the attached config without the above commit, or anything else
I've pushed. I see it with vanilla v4.4, v4.0, v3.0...
I guess it's flagged because the list of dependencies changed, but it's a 4xx
problem, not FSL. 4xx should not claim that suspend/hibernate is possible
with SMP, unless it supports CPU hotplug.
