How to Upgrade to Linux Kernel 4.5 RC1 on Ubuntu Derivative System
Linux Kernel 4.5 RC1 is released, you can upgrade on Ubuntu 16.04 Xenial Xerus, Ubuntu 15.10 wily werewolf, Ubuntu 15.04 vivid Vervet, ubuntu 14.10 Utopic Unicorn, Ubuntu 14.04 Trusty Tahr (LTS)
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 version 4.5 RC1 :
- The statistics look fairly normal too, with drivers being a bit over 70% of the bulk (the big driver areas being gpu, networking, sound, staging, fbdev, but its all over). The shortlog is too big and unwieldly to post, but I'm appending my "mergelog" which credits the maintainers I merge from - not necessarily the people who did the actual individual patches.
- Aside from drivers, we have architecture updates (over half of it being arm - both 32- and 64-bit this time around, the rest is powerpc, x86, mips, s390). On the arch front, it's probably worth mentioning that apparently the arm people have finalized their platform work, and that you really can build a generic ARM kernel for all the ARMv6/7 platforms (and describe the hardware with devicetree). It's been many years in coming. Good job.
- There's also obviously the usual documentation, filesystem, generic networking, and core kernel updates. A number of nice MM cleanuips came in through Andrew this time around, for example, and Al Viro made pathname lookup stay in RCU mode even over symlink traveral.
