Commit 8748270821 ("mm: introduce numa_memblks") has moved
numa_memblks from x86 to the generic code, but LoongArch was left out
of this conversion.
This patch introduces the generic numa_memblks for LoongArch.
In detail:
1. Enable NUMA_MEMBLKS (but disable NUMA_EMU) in Kconfig;
2. Use generic definition for numa_memblk and numa_meminfo;
3. Use generic implementation for numa_add_memblk() and its friends;
4. Use generic implementation for numa_set_distance() and its friends;
5. Use generic implementation for memory_add_physaddr_to_nid() and its
friends.
Note: Disable NUMA_EMU because it needs more efforts and no obvious
demand now.
