1) Install Linux Deploy with following :

UBUNTU BIONIC (ARM64)

2) Install Termux ,Open and execute :

apt install openssh

3) start linux deploy and open termux

ssh usr@ip

4) install git and clone ur kernel

5) install packages :

apt install libncurses5-dev make python gcc g++ grep bc curl gcc-arm-linux-gnueabi

6) export ARCH=arm64
export CROSS_COMPILE_ARM32=arm-linux-gnueabi-

7) go to kernel directory and
make clean && make mrproper

8) ls arch/arm64/configs
and look for u config file (for my redmi note 4 its mido_defconfig)

9) make {ur config} (for me = make mido_defconfig)

10) make menuconfig (for any modifications)

11) make -j(number of cores)
make -j8 (to get max compilation speed)
make -j8 0=out (to seperate source and build files)

12) fix error to get zImage(for arm) and image.gz-dtb(for arm64)
kernel will be built in arch/arm64/boot when u finished compiling
