Results from Linaro’s test farm.
Regressions on arm64 noticed.

GOOD: v4.4.273
BAD: v4.4.274

Regressions found on arm64 juno-r2 and qemu_arm64 device.

Reported-by: Linux Kernel Functional Testing <lkft@xxxxxxxxxx>

step to reproduce:
-------------------------
# boot qemu arm64 and run ltp netns_netlink test.

- cd /opt/ltp
- ./runltp -s netns_netlink

We have started the git bisection script to find the first bad commit
causing these LTP netns test failures.
