memblock tests: add generic NUMA tests for memblock_alloc_exact_nid_raw
Add tests for memblock_alloc_exact_nid_raw() where the simulated physical
memory is set up with multiple NUMA nodes. Additionally, all but one 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:
+ there are no previously reserved regions, but requested node is
too small
+ the requested node is fully reserved
+ the requested node is partially reserved and does not have
enough space
+ 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:
+ range partially overlaps with two different nodes, where the
second node is the requested node
+ range overlaps with multiple nodes along node boundaries, and
the requested node starts after max_addr
+ 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
