Kernel prepatch 6.7-rc8

Linus has released 6.7-rc8 for testing.

So as expected, pretty much nothing happened over the holiday week.
We've got literally just 45 files changed, and almost a third of
those files aren't even kernel code (ie things like selftests,
scripting, Kconfig and maintainer file updates). And some of the
rest is prep-work and cleanups for future (real) changes.

But we do have a couple of real fixes in there, and I suspect we'll
get a few more next week as people come back from their
food-induced torpor.
