Merge branch 'x86-topology-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 topology updates from Ingo Molnar: "Implement multi-die topology support on Intel CPUs and expose the die topology to user-space tooling, by Len Brown, Kan Liang and Zhang Rui. These changes should have no effect on the kernel's existing understanding of topologies, i.e. there should be no behavioral impact on cache, NUMA, scheduler, perf and other topologies and overall system performance" * 'x86-topology-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: perf/x86/intel/rapl: Cosmetic rename internal variables in response to multi-die/pkg support perf/x86/intel/uncore: Cosmetic renames in response to multi-die/pkg support hwmon/coretemp: Cosmetic: Rename internal variables to zones from packages thermal/x86_pkg_temp_thermal: Cosmetic: Rename internal variables to zones from packages perf/x86/intel/cstate: Support multi-die/package perf/x86/intel/rapl: Support multi-die/package perf/x86/intel/uncore: Support multi-die/package topology: Create core_cpus and die_cpus sysfs attributes topology: Create package_cpus sysfs attribute hwmon/coretemp: Support multi-die/package powercap/intel_rapl: Update RAPL domain name and debug messages thermal/x86_pkg_temp_thermal: Support multi-die/package powercap/intel_rapl: Support multi-die/package powercap/intel_rapl: Simplify rapl_find_package() x86/topology: Define topology_logical_die_id() x86/topology: Define topology_die_id() cpu/topology: Export die_id x86/topology: Create topology_max_die_per_package() x86/topology: Add CPUID.1F multi-die/package support
