Driver core / kernfs changes for 6.0-rc1

Here is the set of driver core and kernfs changes for 6.0-rc1.

"biggest" thing in here is some scalability improvements for kernfs for
large systems.  Other than that, included in here are:
	- arch topology and cache info changes that have been reviewed
	  and discussed a lot.
	- potential error path cleanup fixes
	- deferred driver probe cleanups
	- firmware loader cleanups and tweaks
	- documentation updates
	- other small things

All of these have been in the linux-next tree for a while with no
reported problems.
