  Merge patch series "riscv: some CMO alternative related clean up" (2023-07-06 10:32:38 -0700)

----------------------------------------------------------------
RISC-V Patches for the 6.5 Merge Window, Part 2

* A bunch of fixes/cleanups from the first part of the merge window,
  mostly related to ACPI and vector as those were large.
* Some documentation improvements, mostly related to the new code.
* The "riscv,isa" DT key is deprecated.
* Support for link-time dead code elimination.
* Support for minor fault registration in userfaultd.
* A handful of cleanups around CMO alternatives.

----------------------------------------------------------------
The batch from yesterday morning didn't make it to linux-next, I just screwed
up and forgot to move them off staging in time.  They're all fairly small and
still pass my tests, but I don't really like to skip linux-next so I figured
I'd say something.

Aside from that, things look fairly sane for what was a pretty large merge
window.  There's one outstanding bug related to mapping symbols that manifests
in some randconfigs, there's a fix out already [1].  That's not a merge window
regression though, so I think it's safe to proceed.  There's also a handful of
the normal merge window all{yes,mod}config issues, they have fixes on the lists
as well.
