[PATCH v2] powerpc/mm: move a KERN_WARNING message to pr_debug()

[Michael Ellerman]

Hi Laurent,

I'm not sure I'm convinced about this one. It seems like we're just
throwing away the warning because it's annoying.

Something did not work properly, the resize didn't work properly. Right?

Can you explain that more. Isn't the fact that the resize failed "the
real error message"?

This should all be on one line, and formatted as:

Fixes: 7339390d772d ("powerpc/pseries: Don't give a warning when HPT resizing isn't available")

See Documentation/process/submitting-patches.rst for more info and how
to configure git to do it automatically for you.
