How to Upgrade to Linux Kernel 4.2 rc2 on Ubuntu / Linux Mint / Elementary OS

Install/Update and upgrade Linux Kernel 4.2 rc2 (unStable) on Ubuntu 15.04 Vivid Vervet, ubuntu 14.10 Utopic Unicorn, Ubuntu 14.04 Trusty Tahr (LTS), Pinguy OS 14.04, Elementary OS 0.3 Freya and Linux Mint 17.2 Rafaela, Linux Mint 17.1 Rebecca, Linux Mint 17 Qiana

Linux kernel is the essential part of any Linux operating system. It is responsible for resource allocation, low-level hardware interfaces, security, simple communications, basic file system management, and more. Written from scratch by Linus Torvalds (with help from various developers), Linux is a clone of the UNIX operating system. It is geared towards POSIX and Single UNIX Specification compliances.

Includes powerful features

Linux provides users with powerful features, such as true multitasking, multistack networking, shared copy-on-write executables, shared libraries, demand loading, virtual memory, and proper memory management.

Initially designed only for 386/486-based computers, now Linux supports a wide range of architectures, including 64-bit (IA64, AMD64), ARM, ARM64, DEC Alpha, MIPS, SUN Sparc, PowerPC, as well as Amiga and Atari machines.

What New in Linux Kernel 4.2 RC2:

• The rc2 patch is roughly one third drivers (drm being the bulk of it), one third architectures (arm, mips and parisc, a smattering of x86) and one third "misc". That misc pile is mostly filesystems (btrfs) and some timer updates, and then the perf tool build fix that involved just making some of the perf tool infrastructure private to the tool rather than trying to share it with the kernel.
