What is the "official" way to build selftests/mm ?
I tried a few ways, but it never worked, i.e. due to head missing.

1>
cd tools/testing/selftests/mm
make

migration.c:10:10: fatal error: numa.h: No such file or directory
   10 | #include <numa.h>
      |          ^~~~~~~~
compilation terminated.

2>
make headers
make -C tools/testing/selftests

make[1]: Entering directory
'/usr/local/google/home/jeffxu/mm/tools/testing/selftests/mm'
  CC       migration
migration.c:10:10: fatal error: numa.h: No such file or directory
   10 | #include <numa.h>

Thanks!
