hi6220-hikey - arm64: kselftest: * main.sh

Adding Viresh Kumar to Cc, he worked on that testcase.

Viresh, this apparently started failing between v4.4.112 and v4.4.113, but unfortunately there is little information available from the logs above (see https://lkft.validation.linaro.org/scheduler/job/98917), aside this:

The changes that got merged don't seem to be related at all, they are mostly about x86 retpoline support (Spectre mitigation):

I also see a WARN_ON() that triggered in the boot log, but that appears unrelated:
