Hi Xinwei,
Tested kernel debs in comment #9 and cpu and memory stress test are
passed. 1302 processes in `ps aux` after cpu stress test.
If the kernel debs can pass your internal test for crypto module, let me
know and I will propose the patchset to kernel team.

Hi Xinwei,
I build kernel for testing on bug 1932117 and bug 1943301 with 4 patches
backported.

d0228aeb4d65 crypto: hisilicon/sec2 - update SEC initialization and reset
a13c97118749 crypto: hisilicon/sec2 - Add workqueue for SEC driver.
Build the kernel with 3 patches backported, and the test looks good.
https://kernel.ubuntu.com/~ikepanhc/lp1932117.2/
