Works as expected.

Updated rpms and rebooted (note I have also new microcode_ctl). I ran also the test suite (both tests pass) and submitted results.
One of the enhancements comparing to -11 is that it now shows details under /proc/cpuinfo in 'bugs' section - in my case: cpu_meltdown spectre_v1 spectre_v2
