Tejun Heo c73b7d02da crypto: mark crypto workqueues CPU_INTENSIVE
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.

Huang Ying 25c38d3fb9 crypto: api - Use dedicated workqueue for crypto subsystem
Use dedicated workqueue for crypto subsystem

A dedicated workqueue named kcrypto_wq is created to be used by crypto
subsystem. The system shared keventd_wq is not suitable for
encryption/decryption, because of potential starvation problem.
