[PATCH V1 0/4] Urgent fixes for Intel CQM/MBM counting

[Vikas Shivappa]

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

CQM and MBM counters reported some incorrect counts for different
scenarios like interval mode or for multiple perf instances. The
1/4,2/4,3/4 address these issues.

The last patch changes the cqm driver to only support task events as
support for cgroup event was broken - Just reporting a 'not-supported'
error to perf instead of pretending to support and send incorrect counts.

[PATCH 1/4] perf/x86/cqm,mbm: Store cqm,mbm count for all events when
[PATCH 2/4] perf/x86/mbm: Store bytes counted for mbm during recycle
[PATCH 3/4] perf/x86/mbm: Fix mbm counting when RMIDs are reused
[PATCH 4/4] perf/x86/cqm: Support cqm/mbm only for perf events
