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
