Merge branch 'x86-cpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cpu updates from Ingo Molnar: "The biggest changes are an extension of the Intel RDT code to extend it with Intel Memory Bandwidth Allocation CPU support: MBA allows bandwidth allocation between cores, while CBM (already upstream) allows CPU cache partitioning. There's also misc smaller fixes and updates" * 'x86-cpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (23 commits) x86/intel_rdt: Return error for incorrect resource names in schemata x86/intel_rdt: Trim whitespace while parsing schemata input x86/intel_rdt: Fix padding when resource is enabled via mount x86/intel_rdt: Get rid of anon union x86/cpu: Keep model defines sorted by model number x86/intel_rdt/mba: Add schemata file support for MBA x86/intel_rdt: Make schemata file parsers resource specific x86/intel_rdt/mba: Add info directory files for Memory Bandwidth Allocation x86/intel_rdt: Make information files resource specific x86/intel_rdt/mba: Add primary support for Memory Bandwidth Allocation (MBA) x86/intel_rdt/mba: Memory bandwith allocation feature detect x86/intel_rdt: Add resource specific msr update function x86/intel_rdt: Move CBM specific data into a struct x86/intel_rdt: Cleanup namespace to support multiple resource types Documentation, x86: Intel Memory bandwidth allocation x86/intel_rdt: Organize code properly x86/intel_rdt: Init padding only if a device exists x86/intel_rdt: Add cpus_list rdtgroup file x86/intel_rdt: Cleanup kernel-doc x86/intel_rdt: Update schemata read to show data in tabular format ...
