  Merge branch 'misc' into for-next (2026-08-07 11:47:13 +0300)

memblock: updates for 7.3-rc1

Non-urgent fixes:

* Fix calculation of node_spanned_pages when running with kernelcore=mirror
* Properly handle failure to allocate per_cpu_nodestats in
  free_area_init_core_hotplug()
* Fix deferred initialization of the memory map for configurations where
  node's RAM end is not aligned on PAGES_PER_SECTION

Cleanups:

* Remove redundant pageblock_align() call in free_unused_memmap()
* Remove unnecessary invalid range checks in users of memblock iterators.
  Some users of for_each_mem_range() and for_each_mem_pfn_range() verify
  that start < end for each range. This is redundant because memblock
  iterators guarantee to never return an invalid range
* Stop overlapping zones with kernelcore=mirror and align behaviour of
  kernelcore=mirror with other variants of kernelcore=/movablecore=
* Remove redundant updates of numa_nodes_parsed mask in the callers of
  numa_add_memblk(), the latter always updates the mask anyway
* Remove unnecessary initialization of pgdat->per_cpu_nodestats to NULL,
  the variable is reset to the actual value a few lines below
