3.18.12 backported 61ada528dea028331e99e8ceaed87c683ad25de2 ("sched/wait:
Provide infrastructure to deal with nested blocking") from 3.19, causing
the following error on load:
[ 13.588000] compat: exports duplicate symbol woken_wake_function (owned by kernel)
Fix this by guarding it with a check for 3.18.11 or earlier instead of
3.19.
