memblock tests: add top-down 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 of these tests set nid != NUMA_NO_NODE. These tests are run with a top-down allocation direction. The tested scenarios are: Range unrestricted: - region can be allocated in the specific node requested: + there are no previously reserved regions + the requested node is partially reserved but has enough space Range restricted: - region can be allocated in the specific node requested after dropping min_addr: + range partially overlaps with two different nodes, where the first node is the requested node + range partially overlaps with two different nodes, where the requested node ends before min_addr + range overlaps with multiple nodes along node boundaries, and the requested node ends before min_addr Acked-by:David Hildenbrand <david@redhat.com> Signed-off-by:
