How to Upgrade to Linux Kernel 4.1 RC3 on Ubuntu / Linux Mint

How to Install or Upgrade to Linux Kernel 4.1 RC3 on Ubuntu 15.04 vivid Vervet, ubuntu 14.10 Utopic Unicorn, Ubuntu 14.04 Trusty Tahr (LTS) and 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's new in Linux Kernel 4.1 RC3:

• As you can tell, it's mostly drivers, with a smattering of arch updates (mostly ARM). And a smattering of misc stuff: perf tooling, documentation, filesystems. The infiniband update is a noticeable chunk of the drivers, we had some delayed stuff there due to maintainership changes.
• Nothing particularly scary or worrisome going on, although there are little fixes all over. Some of them are regressions from this merge window, and some of them are older. And some of them are so old that I almost thought "if it's been broken since 2011, and you only noticed now, maybe it could have waited for the next merge window". You know who you are (and others will too, if they read the commit messages - your shame is out there).

The source is available now. Binary packages are in the process of being built, and will appear soon at their respective download locations.
