Updated kernel packages fix security vulnerabilities

This kernel update is based on the upstream 4.14.40 and fixes at least the following security issues: On x86, MOV SS and POP SS behave strangely if they encounter a data breakpoint. If this occurs in a KVM guest, KVM incorrectly thinks that a DB instruction was caused by the undocumented ICEBP...
