Subject[PATCH 00/28 V2] Cqm3 patch series(along with MBM support)
Date
Sending the V2 series to address all the feedback that was received in
V1. Apart from that this series adds a patch from Reinette to fix a
global declaration in existing RDT and also fixes some issues where the
prq MSR was not updated when masks or tasks were moved in some cases and
some cleanups.

Acknowledgements:
- Thanks to Thomas for all the feedback on the requirements and
design.
- Thanks to Stephane Eranian <eranian@google.com> and David
Carrillo-Cisneros <davidcc@google.com> for going through all the
churning during requirements and design phase and code reviews.

Patches are based on 4.12

Changes in V2 as per the feedback:
Thanks to Thomas and PeterZ for all the feedback and suggest a lot of
improvements that can be done.
- Improved the RMID limbo list handling to not spend too much time in
the IPIs.
- Fixed a lot of coding convention issues and added comments to better
explain the code.
- Changed naming of the globals to better indicate the enabling and
detecting of features and better organize init code.
- Changed closid to u32 instead of int.
- Made new patches to split the existing ones to make it more readable
- Added functions to contain the reuse code.
- Separated the monitor only related bits from the control and monitor
structure to make it clear in the code that the monitor rdtgroup and
the control groups are different.
