Subject: [PATCH V2 0/3] Urgent fixes for Intel CQM/MBM counting

Sending some urgent fixes for the MBM(memory b/w monitoring) which is
upstreamed from 4.6-rc1. Patches apply on 4.6-rc6.

CQM and MBM counters reported some incorrect counts for different
scenarios like interval mode or for multiple perf instances. 

A second attempt to send V2 as per Peter feedback: 
fixing a few indenting issues and
adding some better changelogs/comments. Removed the patch to send error
for some broken features - since these were broken anyways since 4.1.
Removed the confusing rc_count and st_count and tried to implement close
to the perf way.

[PATCH 1/3] perf/x86/cqm,mbm: Store cqm,mbm count for all events when
[PATCH 2/3] perf/x86/mbm: Fix mbm counting for RMID reuse
[PATCH 3/3] perf/x86/mbm: Fix mbm counting during RMID recycling
