Three new stable kernels

Greg Kroah-Hartman has announced the release of the 4.14.12, 4.9.75, and 4.4.110 stable kernels. The bulk of thechanges are either to fix the mitigations for Meltdown/Spectre (in 4.14.12) or to backportthose mitigations (in the two older kernels). There are apparently known (orsuspected) problems with each of the releases, which Kroah-Hartman is hoping to get shaken out inthe near term. For example, the 4.4.110 announcement warns: "But becareful, there have been some reports of problems with this release during the -rc review cycle. Hopefully all of those issues arenow resolved.So please test, as of right now, it should be 'bug compatible' with the'enterprise' kernel releases with regards to the Meltdown bug and propersupport on all virtual platforms (meaning there is still a vdso issuethat might trip up some old binaries, again, please test!)"
