Subject: [PATCH v2 2/4] memblock tests: add top-down NUMA tests for memblock_alloc_try_nid*
Date:   Fri, 19 Aug 2022 02:05:32 -0700
Message-Id: <957966f06474e3885796247ad1beaa6b3841ebd1.1660897864.git.remckee0@gmail.com>

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, 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
- the specific node requested cannot accommodate the request, but the
  region can be allocated in a different node:
      + there are no previously reserved regions, but node is too small
      + the requested node is fully reserved
      + the requested node is partially reserved and does not have
        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
- region cannot be allocated in the specific node requested, but it can be
  allocated in the requested range:
      + range overlaps with multiple nodes along node boundaries, and the
        requested node ends before min_addr
      + range overlaps with multiple nodes along node boundaries, and the
        requested node starts after max_addr
- region cannot be allocated in the specific node requested, but it can be
  allocated after dropping min_addr:
      + range partially overlaps with two different nodes, where the
        second node is the requested node
