Pull sched.h split-up from Ingo Molnar: "The point of these changes is to significantly reduce the <linux/sched.h> header footprint, to speed up the kernel build and to have a cleaner header structure. After these changes the new <linux/sched.h>'s typical preprocessed size goes down from a previous ~0.68 MB (~22K lines) to ~0.45 MB (~15K lines), which is around 40% faster to build on typical configs. Not much changed from the last version (-v2) posted three weeks ago: I eliminated quirks, backmerged fixes plus I rebased it to an upstream SHA1 from yesterday that includes most changes queued up in -next plus all sched.h changes that were pending from Andrew. I've re-tested the series both on x86 and on cross-arch defconfigs, and did a bisectability test at a number of random points. I tried to test as many build configurations as possible, but some build breakage is probably still...

Pull turbostat utility updates from Rafael Wysocki: "Power management turbostat utility updates. These update turbostat significantly and in particular: - default output is now verbose, --debug is no longer required to get all counters. As a result, some options have been added to specify exactly what output is wanted. - added --quiet to skip system configuration output - added --list, --show and --hide parameters - added --cpu parameter - enhanced Baytrail SoC support - added Gemini Lake SoC support - added sysfs C-state columns Also the symbol definitions in arch/x86/include/asm/intel-family.h and arch/x86/include/asm/msr-index.h are updated and the intel_idle and intel_pstate drivers are modified to use the updated symbols.

Pull more power management updates deom Rafael Wysocki: "These fix two bugs introduced by recent power management updates (in the cpuidle menu governor and intel_pstate) and a few other issues, clean up things and remove unused code.

Now that <linux/sched.h> dependencies have been sorted out, do various trivial cleanups: - remove unnecessary structure predeclarations - fix various typos - update comments where necessary - remove pointless comments - use consistent types - tabulate consistently - use a consistent comment style - clean up the header section a bit - use a consistent style of a single field per line - remove line-breaks where they make the code look worse - etc ... No change in functionality. Acked-by:
