This patch series changes how kernel derives cpu "package" from package-as-socket to package-as-die in order to fix following issues on AMD family17h multi-die processor platforms:
* irqbalance fails to allocating IRQs to individual CPU within the die. * The scheduler fails to load-balance across 8 threads within a die (e.g. running 8-thread application w/ taskset -c 0-7 ) with the DIE schedule domain omitted due to x86_has_numa_in_package. These issues are fixed when properly intepretes package as DIE. This series has also been tested on existing AMD systems w/ family15h and family10h multi-die processors.
