Merge tag 'memblock-v6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock
Pull mm-init update from Mike Rapoport:
"Simplify deferred initialization of struct pages
Refactor and simplify deferred initialization of the memory map.
Beside the negative diffstat it gives 3ms (55ms vs 58ms) reduction in
the initialization of deferred pages on single node system with 64GiB
of RAM"
* tag 'memblock-v6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock:
memblock: drop for_each_free_mem_pfn_range_in_zone_from()
mm/mm_init: drop deferred_init_maxorder()
mm/mm_init: deferred_init_memmap: use a job per zone
mm/mm_init: use deferred_init_memmap_chunk() in deferred_grow_zone()
