HARDWARE --
The ARC architecture updates for the Linux 4.2 kernel have landed.

With the ARC architecture updates in Linux 4.2 comes support for HS38 cores, which in turn are based on the Synopsys next-gen ISA known as ARCv2. The ARCv2 ISA is faster and more feature-rich than their original instruction set architecture. The HS38 cores have a 10-stage pipeline core with MMU support, SMP up to four cores, and other new features. The HS38 processor is still 32-bit and is "optimized for high-performance embedded applications running Linux."

The Linux 4.2 pull also adds support for the AXS101 and AXS103 ARC software development platforms.

Those interested in the ARC architecture updates for the Linux 4.2 kernel can find all of the details via this pull request.
