Description of changes:
[2.27-41.base.0.3.el7_7.1]
- CVE-2018-12207 / Intel SKX102
- Introduce the following gas options:
-malign-branch
-malign-branch-boundary
-malign-branch-prefix-size
-mbranches-within-32B-boundaries
- Lessen the performance hit due to the Mitigation of Intel's JCC Erratum by
backporting the patch series that teach gas not to place various jump
instructions at the end of 32 byte boundries or across such boundaries.
