After checkbox CPU stress test, it takes 2min 30sec to login.
Checks system resources and find out there are more then 900000
processes in output of `ps aux` and most of them are [hisi_qm].

In order to fix this issue, we need to backport patch for adding
workqueue and using 1 wq per qm. Patch "Unify hardware error
init/uninit into QM" is pulled in because of patch dependency.

Another issue is that resetting crypto module can not work. To fix
this issue we need to backport patch "Update SEC init and reset".

Longfang Liu (1):
  crypto: hisilicon/sec2 - update SEC initialization and reset

Shukun Tan (2):
  crypto: hisilicon - Unify hardware error init/uninit into QM
  crypto: hisilicon - Use one workqueue per qm instead of per qp

Ye Kai (1):
  crypto: hisilicon/sec2 - Add workqueue for SEC driver.
