This security issue was fixed:
- CVE-2018-3646: Systems with microprocessors utilizing speculative
 execution and address translations may have allowed unauthorized
 disclosure of information residing in the L1 data cache to an attacker
 with local user access with guest OS privilege via a terminal page fault
 and a side-channel analysis (bsc#1091107, bsc#1027519).
These non-security issues were fixed:
- bsc#1102116: SSBD is not virtualized for guests
- bsc#1092631: Preserve the xl dmesg output after boot for determining
 what speculative mitigations have been detected by the hypervisor.
- bsc#1101684: Make xen able to disable the visibility of the new CPU
 flags.");
