[PATCH 00/28 V2] Cqm3 patch series(along with MBM support)

[Vikas Shivappa <vikas.shivappa@linux.intel.com>]

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.
