This is a pull request for the update of Xenial to upstream stable release 4.4.130.
This update pulls in upstream's version of the spectre mitigation for s390
which doesn't provide a 'nogmb' kernel parameter. The following two SAUCE
patches add the missing features back so that the original Xenial behavior is
preserved:
* UBUNTU: SAUCE: s390: print messages for gmb and nobp
* UBUNTU: SAUCE: s390: Add 'nogmb' kernel parameter
Skipped the following patch (already applied):
* KVM: s390: wire up bpb feature
Some patches required trivial context adjustement.
Compile-tested all supported architectures.
