kcrypto_wq and pcrypt->wq's are used to run ciphers and may consume considerable amount of CPU cycles. Mark both as CPU_INTENSIVE so that they don't block other work items. As the workqueues are primarily used to burn CPU cycles, concurrency levels shouldn't matter much and are left at 1. A higher value may be beneficial and needs investigation.
