Hi, I'm reporting a regression in linux-next that was introduced between 20251114 and 20251117.

This was reported here too - https://lore.kernel.org/all/69158bb1.a70a0220.3124cb.001e.GAE@google.com/ (local) Looks like it should be fixed with v3, which was posted just yesterday... https://lore.kernel.org/all/20251117173530.43293-2-vishal.moola@gmail.com/ (local) So, I guess, latest linux-next should not show this warning on ppc64le either. -ritesh
