[Xiaomi Redmi Note 3 [Snapdragon] ROMs, Kernels, Re] MOVZX:
I guess I knew a fix for the CPU Hot-Plug feature (A72), I take some init files from Stock MiUI (Qualcomm related) and put it inside /system/etc/init.d set permission 755 and CPU Hot-Plug (A72) is working!

Here is the init.qcom.post_boot.sh script, I renamed it into 01PostBoot and put it inside /system/etc/init.d:

You might want to try for it while we wait official CM13.0 with native CPU Hot-Plug features, it worked well on my phone with every CM-based ROMs out there :)

See it in action in RR CM-based ROM.
