Stable kernel updates

Stable kernels 4.16.14, 4.14.48, and 4.9.106 have been released. The 4.16 and 4.14kernels contain the usual set of important fixes. "Not everyone whouses 4.9 needs to upgrade here, it's a big sync of the objtool codebase tomake future maintenance of 4.9.y easier over time, that's all. But ofcourse, updating and verifying that nothing broke is always appreciated:)"
