It appears you fetched v4, not v5. I noticed it from the threading of your
report that was threaded in the v4 thread, and also the github url: above.
In v4, pcpu_spin_trylock_irqsave() was missing an unpin, and indeed it's
missing in the github branch you were testing:
https://github.com/intel-lab-lkp/linux/commit/2bd8eec68f740608db5ea58ecff06965228764cb#diff-cef95765dfd76e5f9c9f0faebfa683edf904d0c3de71547ae8c3ea14418c1e38R187
v5 should be fine:
