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 left - but it should be mostly
limited to architectures that have no cross-compiler binaries
available on kernel.org, and non-default configurations"

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

If we add <linux/uidgid.h> then <linux/sched/user.h> becomes a
self-contained header and users of it either don't need <linux/sched.h>
or have already included it.
This reduces the size of the header dependency graph.

The <linux/sched/autogroup.h> file is a largely self-contained header and users of

Add a 'task_struct' predeclaration to make it build standalone.
This reduces the size of the header dependency graph.

sched_exec() better fits into the task lifetime APIs than into the core scheduler
APIs.
This reduces the size of <linux/sched.h> a bit.

Unclutter <linux/sched.h> some more.
Also move the CONFIG_ARCH_WANT_BATCHED_UNMAP_TLB_FLUSH condition inside the
