Merge tag 'memblock-v6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock

Pull memblock updates from Mike Rapoport:
 "Extend test coverage:

   - add tests that trigger reallocation of memblock structures from
     memblock itself via memblock_double_array()

   - add tests for memblock_alloc_exact_nid_raw() that verify that
     requested node and memory range constraints are respected"

* tag 'memblock-v6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock:
  memblock tests: remove completed TODO item

 TODO
 =====
 
-1. Add tests trying to memblock_add() or memblock_reserve() 129th region.
-   This will trigger memblock_double_array(), make sure it succeeds.
-   *Important:* These tests require valid memory ranges, use dummy physical
-                memory block from common.c to implement them. It is also very
-                likely that the current MEM_SIZE won't be enough for these
-                test cases. Use realloc to adjust the size accordingly.
-
-2. Add test cases using this functions (implement them for both directions):
-   + memblock_alloc_raw()
-   + memblock_alloc_exact_nid_raw()
-   + memblock_alloc_try_nid_raw()
-
-3. Add tests for memblock_alloc_node() to check if the correct NUMA node is set
+1. Add tests for memblock_alloc_node() to check if the correct NUMA node is set
    for the new region
