I didn't really get to think about the actual patchset. From a very
quick glance I am wondering whether we need to optimize as there are
usually only small amount of numa nodes. But I am quite busy so I cannot
really do any claims.

Anyway, you can test this even without NUMA HW. Have a look at numa=fake
option (numa_emu_cmdline). Or you can use kvm/qemu which provides easy
ways to setup a NUMA capable virtual machine.
