[Q] Xposed module for lollipop 5.1.1

Hi,
I am using AICP 5.1.1 rom on my Mi 4. I saw a thread for unofficial version of Xposed module for LP 5.1.1. There are 3 files given :
File Type: zip xposed-v71-sdk22-arm-by-romracer-20150816.zip
File Type: zip xposed-v71-sdk22-arm64-by-romracer-20150816.zip
File Type: zip xposed-v71-sdk22-x86-by-romracer-20150816.zip

Which is the correct file for Mi 4?
