From: Dave Hansen <dave.han...@linux.intel.com> The /sys/devices/system/cpu/cpu*/topology/core_siblings* files were previously built from the "cpu_core_map". That mask is deeply connected to the sched domains internal multi-core (MC) level, which is now become disconnected from the actual CPU package.
We have a new "cpu_package_map" which has the sole purpose of tracking which package the CPU is in and is unconnected to the scheduler. We will now build those sysfs with information from the new package map. Note: this also realigns the sysfs files with their documentation in Documentation/ABI.
