[Kernel][Archlinux] Replace new kernel method

1. Install package
   pacman -S bc
   
   
2. Download kernel source
   tar xvf linux-4.3.2.tar.xz -C /usr/src/
   cd /usr/src//linux-4.3.2/
   make mrproper (Ensures that the kernel tree is absolutely clean.)
   
   
3. Use system configuration file to compile kernel
   zcat /proc/config.gz > .config
   
4. Start to compile
   make
   make modules_install
   This copies the compiled modules into /lib/modules/ARCH-X.X.X/
   
5. Copy the kernel to /boot directory
   cp -v arch/x86/boot/bzImage /boot/vmlinuz-ARCH-4.3.2
   
6. Make initial RAM disk
   mkinitcpio -k FullKernelName -c /etc/mkinitcpio.conf -g /boot/initramfs-YourKernelName.img
   
   Check out which is FullKernelName under /lib/modules
   I have 4.3.2-ARCH-4.3.2 which I create and under my /lib/modules.
   
   Ex:
   sudo mkinitcpio -k 4.3.2-ARCH-4.3.2 -c /etc/mkinitcpio.conf -g /boot/initramfs-linux-ARCH-4.3.2
   ==> Starting build: 4.3.2-ARCH-4.3.2
   -> Running build hook: [base]
   -> Running build hook: [udev]
   -> Running build hook: [autodetect]
   -> Running build hook: [modconf]
   -> Running build hook: [block]
   -> Running build hook: [filesystems]
   -> Running build hook: [keyboard]
   -> Running build hook: [fsck]
   ==> Generating module dependencies
   ==> Creating gzip-compressed initcpio image: /boot/initramfs-linux-ARCH-4.3.2
   ==> Image generation successful
   
7. Switch kernel to new one (Quick method)
   initramfs-linux-ARCH-4.3.2 (size: 3.6M) (Initial RAM disk)
   vmlinuz-ARCH-4.3.2 (size: 4.4M) (Kernel)
   
   cd /boot
   
   Backup the original one
   cp vmlinuz-linux{,.ori}
   cp initramfs-linux.img{,.ori}
   
   
   Use new kernel to replace old one
   cp vmlinuz-ARCH-4.3.2 vmlinuz-linux
   cp initramfs-linux-ARCH-4.3.2 initramfs-linux.img
