			As alluded to above, all I really wanted to do was tweak the kernel config to enable CONFIG_FTRACE. The way I did that was to enter the directory the kernel source is in: ~/android/system/kernel/samsung/smdk4412, then copied the default config for my phone (arch/arm/configs/cyanogenmod_t0lte_defconfig) to .config. After that I could run make menuconfig as normal. For ease of examination I forked the kernel repo and stored the distinct changes I made to the config here.

			After making tweaks with make menuconfig, I copied .config back to arch/arm/configs/cyanogenmod_t0lte_defconfig. To build the boot image I ran the following set of commands (which I put in a bash script:)

			#!/bin/bash

			set -e

			cd ~/android/system
			make clean
			cd kernel/samsung/smdk4412
			make mrproper
			cd ~/android/system
			make -j8 bootimage

			Note that I do not use mka. Some of the android build manuals recommend mka, but I found it was much less reliable than regular make, so I abandoned it.

Ubah konfigurasi kernel

	=====Ubah konfigurasi kernel=====		=====Ubah konfigurasi kernel=====
	The kernel configuration file used during the build process is referenced in <code>TARGET_KERNEL_CONFIG</code> variable in ''device/vendor-name/device-name/BoardConfig.mk''. It generally points to ''kernel/vendor-name/kernel-name/arch/arm/configs/cyanogenmod_device-name_deconfig''.

	~~To make a custom~~ kernel ~~configuration file, you can use the configuration~~ build ~~tools from the kernel dir, e.g.~~ <code>~~make menuconfig~~</code>~~, and save the resulting hidden~~ ''.~~config~~'' ~~file to the location specified in <code>TARGET_KERNEL_CONFIG<~~/~~code>. Then run <code>make mrproper<~~/~~code> from the~~ kernel ~~dir and go back to the CM android source root dir (<code>croot<~~/~~code>) before building~~.		File konfigurasi kernel yang digunakan saat proses build biasanya di acu di <code>TARGET_KERNEL_CONFIG</code> variabel di ''device/vendor-name/device-name/BoardConfig.mk''. Biasanya menunjuk pada ''kernel/vendor-name/kernel-name/arch/arm/configs/cyanogenmod_device-name_deconfig''.

			Untuk membuat file konfigurasi kernel yang custom, kita dapat menggunakan tool untuk build konfigurasi di directory kernel, misalnya,

			<code>make menuconfig</code>

			dan simpan hasilnya di file hidden ''.config'' di lokasi yang ditunjukan oleh <code>TARGET_KERNEL_CONFIG</code>. Kemudian jalankan <code>make mrproper</code> dari directory kernel dan kembali ke directory root CM android source (<code>croot</code>) sebelum melakukan building.
