This patch can't work well with some older CPUs, and I find one N6005 (Inte=
l JSP).
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.
