[GIT,PULL] header cleanups for 6.8

  Hi Linus, here's some header cleanups, as discussed.

Nothing drastic has changed since it was mailed out, wanted to give this
plenty of soak time in -next.

There were two merge conflicts in arch headers in next; they looked
pretty trivial. But now I'm wondering - do we have standard
tools/process for recording what the merge conflict and resolution were?
I'm sure we must.

The following changes since commit a39b6ac3781d46ba18193c9dbb2110f31e9bffe9:

  Linux 6.7-rc5 (2023-12-10 14:33:40 -0800)

  Kill sched.h dependency on rcupdate.h (2023-12-27 11:50:20 -0500)

----------------------------------------------------------------
header cleanups for 6.8

The goal is to get sched.h down to a type only header, so the main thing
happening in this patchset is splitting out various _types.h headers and
dependency fixups, as well as moving some things out of sched.h to
better locations.

This is prep work for the memory allocation profiling patchset which
adds new sched.h interdepencencies.

Testing - it's been in -next, and fixes from pretty much all
architectures have percolated in - nothing major.

For simple conflicts (like these) the easiest thing to do is just provide
lore URLs to my notifications:

https://lore.kernel.org/all/20231218170015.6018162e@canb.auug.org.au/
https://lore.kernel.org/all/20231218170547.5714468f@canb.auug.org.au/

for more complex cases, you might want to do the merge with Linus' tree in a
temporary branch of your tree and add a note pointing that out in case Linus
wants to check his own resolutions against yours.
