   8 commit ea01668f9f43021b28b3f4d5ffad50106a1e1301 upstream.
   9
  10 Adjust the last two rows in the table that display possible values when
  11 MDS mitigation is enabled. They both were slightly innacurate.
  12
  13 In addition, convert the table of possible values and their descriptions
  14 to a list-table. The simple table format uses the top border of equals
  15 signs to determine cell width which resulted in the first column being
  16 far too wide in comparison to the second column that contained the
  17 majority of the text.
