This JSP cpu is not a hybrid cpu architecture, but the high cpu id is 0x1b = with 0x20000000 which meet the small core condition in the patch, but kerne= l got crashed on this cpu. We need a better condition to pick up the E cores to make sure the kernel c= an be compatible with all older Non-Hybrid CPUs. Internal Use - Confidential
