Merge tag 'fixes-2024-06-13' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock
Pull memblock fixes from Mike Rapoport:
"Fix validation of NUMA coverage.
memblock_validate_numa_coverage() was checking for a unset node ID
using NUMA_NO_NODE, but x86 used MAX_NUMNODES when no node ID was
specified by buggy firmware.
Update memblock to substitute MAX_NUMNODES with NUMA_NO_NODE in
memblock_set_node() and use NUMA_NO_NODE in x86::numa_init()"
* tag 'fixes-2024-06-13' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock:
x86/mm/numa: Use NUMA_NO_NODE when calling memblock_set_node()
memblock: make memblock_set_node() also warn about use of MAX_NUMNODES
