I have working version but Google Play Store always updates no matter what I do and Google just doesn't want to fix the issue,like they want to stay on 4.7 GCC toolchain forever.
Liquidsmooth is AOSP based,I checked their git it looks that it is O3 compatible and since this kernel is already build with Sabermod toolchain 4.10 I think everything should go smooth.
I can lower voltage min limit but its set by Qualcomm like that for a reason.
I will put your voltage table into kernel as soon you finish it so there won't be a bunch of useless kernels.
I don't know Chinese but by some logical meaning I found that MIUI 6 will start rolling out soon and that Xiaomi MI3 TD should get it in 2-3 weeks and I think they confirmed MIUI 6 to be 4.1 for Xiaomi MI2.
