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 and David Carrillo-Cisneros 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.
