When I tried this in 3.14.x the kernel would lock up immediately during
boot (not even a console). This may or may not have to do with me also
using the BFS scheduler, but it's IMHO something that should be
double-checked.
I also tried to backport the necessary macros but that went nowhere
fast, since they ended up pulling in most of the rcu-task stuff..
