Hi.

That said, as the current plan is to MFC this change to stable/14 before releng/14.3, more testing, with possibly different hardware, is always welcome and would be great.

Currently just a FYI:

I myself don't using amdgpu driver, but tried to cherry-pick (not
`git cherry-pick, but tried applying diff as a patch) it on stable/14,
amd64 at commit b429d50df97bc6f85373d4bd4ffca7e7078b3fe8, which failed
on sys/compat/linuxkpi/common/src/linux_page.c.

 *Just to be sure it doesn't harm graphics/nvidia-drm-*-kmod once it is
  MFC'ed, as I cannot take enough time to test on main, and current
  state of my main branch is older than it.


There seems to be a prerequisite, at least commit
2619c5ccfe1f7889f0241916bd17d06340142b05. Not sure more to be required,
nor some part of the commit does harm or not, as I've stopped
investigating this for now.
