Bug Description

Google has sent a new cqm patch with a lot of fixes to the existing cqm which is upstream. The MBM was based on the old cqm and now needs to be ported on top of the new version of cqm. The google patch is enormous and hence mbm requires a lot of changes to work on top of it. However This wont impact the openstack usage of cqm/mbm as the name of the events would still be the same and they can just be used like before - only that there may be some features which wernt working will work now.

Platform: BDW-EP or BDW-EX

upstream schedule: 4.13 kernel

From Upstream:
Not need full port of MBM as we rewrote the google cqm patch series. new series not does not remove mbm, So mbm full port is not required if our series is accepted.

Keep tune for the new cqm series to lkml
