The 4.15 kernel is out

Linus has released the 4.15 kernel."After a release cycle that was unusual in so many (bad) ways, thislast week was really pleasant. Quiet and small, and no last-minutepanics, just small fixes for various issues. I never got a feelingthat I'd need to extend things by yet another week, and 4.15 looksfine to me."Some of the more significant features in this release include:the long-awaited CPU controller for theversion-2 control-group interface,significant live-patching improvements,initial support for the RISC-V architecture,support for AMD's secure encrypted virtualization feature, andthe MAP_SYNC mechanism for workingwith nonvolatile memory.This release also, of course, includes mitigations for the Meltdown and Spectre variant-2vulnerabilities though, as Linus points out in the announcement, thework of dealing with these issues is not yet done.
