Hi guys! Here comes the first custom kernel in xda for L-preview
I'm presenting my personal kernel Code_Blue, that started as an addon for Purity ROM, called Purified Kernel.
Some of you that know me from other Nexus devices asked me to bring back the project, so I (finally) did.
My releases are Dragon_Shield powered and I'm going to share them with you.
All I want is full smoothness, performance and battery on my hammerhead, so I build always with Linaro optimized Cortex A15 toolchains.
This time I aim for a "stockish" feel lean build and for stability purposes I will stay with GCC 4.9.2 for now.
Code is based of android-msm-hammerhead-3.4-l-preview, forked from android/kernel_msm.
Useful and powerful picks are mandatory
Be sure to join Code_Blue users G+ community
You keep the spirit alive!

Download latest Code_Blue Kernel zip on Test folder, flash in recovery and profit :highfive:
No mirrors allowed. Don't post hardlinks, use original links.
Changelog is available @ website also.
Builds are coded as follows:
- test only for now on tests folder, no changelog, build with Linaro Cortex-A15 4.9.2 to minimize issues in troubleshoot.
Warning: If you come from other kernel, you should dirty flash your ROM before flashing Code_Blue zip to avoid problems.
Reflash ROM -> flash SuperSU -> Boot device -> flash Code_Blue.
Also uninstall or clean data of any kernel control app you're using.
