[kvm-unit-tests] arm/arm64: psci_cpu_on_test failures with tcg

[Nikos Nikoleris <nikos.nikoleris@xxxxxxx>]

Hi,

I noticed that in the latest master the psci_cpu_on_test fails randomly 
for both arm and arm64 with tcg.

If I do:

$> for i in `seq 1 100`; do ACCEL=tcg MAX_SMP=8 ./run_tests.sh psci; 
done | grep FAIL

About 10 of the 100 runs fail for the arm and arm64 builds of the test. 
I had a look and I am not sure I understand why. When I run the test 
with kvm, I don't get any failures. Does anyone have an idea what could 
be causing this?

Thanks,

Nikos
