As phys_to_virt() relies on m68k_memoffset and module_fixup(), it must
not be called before paging_init(). Hence postpone the phys_to_virt
handling for the initial ramdisk until after calling paging_init().
Thanks for debugging this issue.
Np, you're welcome.
While at it, reduce #ifdef clutter by using IS_ENABLED() instead.
Fixes: 376e3fdecb0dcae2 ("m68k: Enable memtest functionality")
I apologise for the trouble caused by that patch.
Does that count as an Acked-by? ;-)
Well, git log | grep suggested Mea-culpa-by and some others...
