By default, the MTRR size is not set correctly and the MDS bug is present. To set the MTRR size correctly and avoid memory loss, set the following kernel parameters:

enable_mtrr_cleanup mtrr_spare_reg_nr=1 mtrr_gran_size=32M mtrr_chunk_size=128M

To mitigate MDS, add mds=full,nosmt. The nosmt option disables simultaneous multi-threading so if the decrease in performance is too much, use mds=full instead.
