RHEL will include a backport of the kernel patch "do not raise timer softirq unconditionally (spinlockless version)" (https://lkml.org/lkml/2019/4/15/1215), but disabled by default. Enable it in realtime-virtual-{host/guest} profiles as it decreases maximum cyclictest latency. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
