Phoronix announced yesterday [phoronix.com], 11 December 2016, and Linus confirms [iu.edu], the release of Linux Kernel version 4.9 at Kernel.org [kernel.org].

Highlights listed by Phoronix [phoronix.com] include:

- Memory Protection Keys (MPK) are now mainlined.

- Support for vmapped kernel stacks, one of Torvalds' favorite features for Linux 4.9.

- Experimental AMDGPU Southern Islands support / GCN 1.0 for AMDGPU, but keep in mind it's disabled by default and needs to be set at kernel build-time, similar to the experimental GCN 1.1 / CIK support for AMDGPU DRM.

- Improved P-State performance for some Intel Atom CPUs.

- AMDGPU virtual display support.

- Support for 29 more ARM machines by the mainline Linux kernel.

- The introduction of a new subsystem, Greybus.

- Various file-system improvements.

Your humble submitter is posting the story from his system running a freshly-compiled 4.9 kernel, so it's guaranteed to be a real thing.
