It will eventually please be patient as L hasn't even been out a month yet everyone is still working on it and implementing new features for custom roms etc...
Just thought I'd give a shout-out to this amazing kernel as I flashed it yesterday along with the latest CM11 nightly. I have to say, even though this kernel hasn't been updated in months, it is still (IMO) the best KitKat kernel out there for the Yuga. It has plenty of options in the kernel settings and most importantly, the battery life is the best available without sacrificing performance. Device doesn't come close to heating up as much as it usually does after modifying the Intelli-thermal settings. Again, still the best usable kernel out there for the Yuga.
EDIT: Wow, the difference in battery life of this kernel vs. others is ridiculous. With other kernels, I can only watch 2 1/2 episodes of Breaking Bad on Netflix before the battery gives in. With this kernel, I can easily watch 5-6 epsiodes while still having a few percentage left to rush and put the phone on charge, lol. Again, excellent job, Thomas. Sad to see you move on to another device. However, your legacy for the Yuga is sincerely preserved.
For the guys having build problems try this:
1. rm -rf kernel/sony/apq8064
2. cd kernel/sony/apq8064 && make mrproper
3. rm -rf out/target/product/yuga/obj/KERNEL_OBJ (or just a make clobber for everything)
4. repo sync and build
Should help, as I just tried a build from clobber and had no problems.
