Hammerhead AKA Nexus 5 Hybrid Kernel

What is a Hybrid?

Hybrid kernel means the core although still has the 3.4.0 kernel label, it has incorporated many advanced features available only on Linux 3.8+ and beyond. It has backported many of those advanced features for Linux 3.4, hence the name hybrid!

Here's the flashable zip file

m - mainline with stock CPU/GPU frequencies
u - ultimate, overclocked CPU 2.5GHz+

sysfs interface for controlling this kernel:

general format:

xxx is the value, can be integer or text depending on the yyy.
(It's pretty obvious if you view the sysfs entry first to see the values it's expecting)

echo xxx > /sys/yyy/yyy/yyy
