This error is caused by commit 677ceea32cf1d8ba9a4870bc58079cd7e7f77558
("sched: prioritize non-migratable tasks over migratable ones") in the
sched tree (sched/for-akpm).  This commit is either just wrong, is was
misrebased, or is just badly out of order.  It introduces a use of
cpupri_find, but the function is not defined until commit
ea9b3c95b7c666d4658a139b88587269e5baa647 ("sched: use a 2-d bitmap for
searching lowest-pri CPU") about 146 commits later ...
