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 Acked-by:David Hildenbrand <david@redhat.com> Signed-off-by:
