2019-05-14Documentation: Move L1TF to separate directoryThomas Gleixner
commit 65fd4cb65b2dad97feb8330b6690445910b56d6a upstream. Move L!TF to a separate directory so the MDS stuff can be added at the side. Otherwise the all hardware vulnerabilites have their own top level entry. Should have done that right away.
