All commits are from Googles android-mainline branch, backported where required, but mostly unchanged and I have the upstream discussions from the kernel ML for reference. If you are curious the 38 commits I want to backport to reduce the divergence and then fix that CVE can be found at https://github.com/Flamefire/android_kernel_sony_msm8998/pull/24.
