"resource, kunit: add test case for region_intersects" is the culprit. Yes. Although the definition in include/linux/mm.h introduced in commit ea72ce5da228 ("x86/kaslr: Expose and use the end of the physical memory address space") doesn't compile on m68k. There are no users of PHYSMEM_END before patch "resource, kunit: add test case for region_intersects". This can be fixed via the following patch. ---------------------------------8<--------------------------------------
