[ROM][04/08][CM11.0][Linaro][O3][MeowKernel][TWRP][Fidelity]CM11.0 - Fidelity Edition

Cheers to the first Linaro fully optimized KitKat 4.4.4 ROM I officially released. It took me a few months to fix my phone and get everything working below.

Features:
-jeroenqui’s Meow Kernel
-TWRP 2.7 Recovery
-Changed audio priority level to highest possible
-Compiled using latest Linaro toolchain version 4.7 and its own NDK
-Compiled with Linaro’s customized O3 optimizations with strict aliasing for both ROM and kernel
-Most strict-aliasing fixes are actual fixes from SlimSaber and my own
-High performance compiler flags optimizations
-Added bionic/framework optimizations from Linaro commits
-Fidelity Driver optimizations having
|-Added board audio optimizations for low latency/fluence/separated audio
|-Increased kernel’s audio clock synchronization frequency
|-Removed start threshold in HAL layer
|-Default sampling rate is set to 44100Hz
|-Reduce number of periods in kernel configuration

This ROM doesn’t come with Google apps so flash it after this ROM if you intend to use them. Using Fidelity Z 6.0 with this ROM is highly recommended.
