kho_scratch_migratetype(), defined in include/linux/memblock.h uses enum migratetype. This breaks build for memblock tests with: ./linux/memblock.h:634:73: error: parameter 2 (‘mt’) has incomplete type 634 | enum migratetype mt) Fix it by defining enum migratetype and MIGRATE_CMA. As is the case with the other headers in tools/testing/memblock, do not bring in the whole thing, only what is needed.
