Four new speculative execution information leak issues have been
identified in Intel CPUs. (bsc#1111331)

CVE-2018-12126: Microarchitectural Store Buffer Data Sampling (MSBDS)

CVE-2018-12127: Microarchitectural Fill Buffer Data Sampling (MFBDS)

CVE-2018-12130: Microarchitectural Load Port Data Sampling (MLPDS)

CVE-2019-11091: Microarchitectural Data Sampling Uncacheable Memory
(MDSUM)

These updates contain the libvirt adjustments, that pass through the
new 'md-clear' CPU flag (bsc#1135273).
