In order to avoid functional breakage of mis-programmed applications that
have grown to depend on unused MOCS entries, we are programming
those entries to be equal to fully cached ("L3 + LLC") entry.

These reserved and unspecified entries should not be used as they may be
changed to less performant variants with better coherency in the future
if more entries are needed.

I made some mistake in header of patch,Correcting that may leads to a
new  entry in patchwork. Please follow
https://patchwork.freedesktop.org/patch/368699/?series=78012&rev=1
to get details of that discussion.
