Hi Hanjun,
a update here, tested on 4.9,
a update here, tested on 4.9,
- Applied Ard's two patches only
- Applied Robert's patch only
Both of them can work fine on D05 with NUMA enabled, which means
boot ok and LTP MM stress test is passed.
It's not related to this patch set.
LTP "cpuset01" test crashes with latest 4.9, 4.10-rc1 and 4.10-rc2 kernels on Thunderx 2S . Do you see any such behaviour on D05.

Any idea what might be causing this issue.

I'm not familiar with memory management, it's up to you guys to make
a decision :)
