mm: numa_memblks: Identify the accurate NUMA ID of CFMW (2026-02-14 09:29:12 +0200)
----------------------------------------------------------------
memblock: numa_memblks: fix detection of NUMA node for CXL windows
phys_to_target_node() may assign a CXL Fixed Memory Window to the wrong NUMA
node when a CXL node resides in the gap of discontinuous System RAM node.
Fix this by checking both numa_meminfo and numa_reserved_meminfo, preferring
the reserved NID when the address appears in both.
