Add tests for memblock_alloc_try_nid() and memblock_alloc_try_nid_raw()
where the simulated physical memory is set up with multiple NUMA nodes.
Additionally, two of these tests set nid != NUMA_NO_NODE. All tests are
run for both top-down and bottom-up allocation directions.
The tested scenarios are:
Range unrestricted:
- region cannot be allocated:
+ none of the nodes have enough memory to allocate the region
Range restricted:
- region can be allocated in the specific node requested without dropping
min_addr:
+ the range fully overlaps with the node, and there are adjacent
reserved regions
- region cannot be allocated:
+ nid is set to NUMA_NO_NODE and the total range can fit the region,
but the range is split between two nodes and everything else is
reserved
