  Merge patch series "riscv: hwprobe: add Zicond, Zacas and Ztso support" (2024-01-09 20:14:51 -0800)

----------------------------------------------------------------
RISC-V Patches for the 6.8 Merge Window, Part 1

* Support for many new extensions in hwprobe, along with a handful of
  cleanups.
* Various cleanups to our page table handling code, so we alwayse use
  {READ,WRITE}_ONCE.
* Support for the which-cpus flavor of hwprobe.
* Support for XIP kernels has been resurrected.

----------------------------------------------------------------
There will almost certainly be a part 2 next week, I've already got a few
things in for-next and there's some more on the mailing lists to get through.

I think the only odd thing here is that I merged in my fixes branch, which I
don't usually do.  I just ended up not being very productive over the holidays
and missed the last few RCs, so I figured it'd be best to just merge them in
rather than cherry pick them over.
