      Pull memblock fix from Mike Rapoport:
       "memblock: always release pages to the buddy allocator in
        memblock_free_late()
      
        If CONFIG_DEFERRED_STRUCT_PAGE_INIT is enabled, memblock_free_pages()
        only releases pages to the buddy allocator if they are not in the
        deferred range. This is correct for free pages (as defined by
        for_each_free_mem_pfn_range_in_zone()) because free pages in the
        deferred range will be initialized and released as part of the
        deferred init process.
      
        memblock_free_pages() is called by memblock_free_late(), which is used
        to free reserved ranges after memblock_free_all() has run. All pages
        in reserved ranges have been initialized at that point, and
        accordingly, those pages are not touched by the deferred init process.
      
        This means that currently, if the pages that memblock_free_late()
        intends to release are in the deferred range, they will never be
        released to the buddy allocator. They will forever be reserved.
      
        In addition, memblock_free_pages() calls kmsan_memblock_free_pages(),
        which is also correct for free pages but is not correct for reserved
        pages. KMSAN metadata for reserved pages is initialized by
        kmsan_init_shadow(), which runs shortly before memblock_free_all().
      
        For both of these reasons, memblock_free_pages() should only be called
        for free pages, and memblock_free_late() should call
        __free_pages_core() directly instead.
      
        One case where this issue can occur in the wild is EFI boot on x86_64.
        The x86 EFI code reserves all EFI boot services memory ranges via
        memblock_reserve() and frees them later via memblock_free_late()
        (efi_reserve_boot_services() and efi_free_boot_services(),
        respectively).
      
        If any of those ranges happens to fall within the deferred init range,
        the pages will not be released and that memory will be unavailable.
      
        For example, on an Amazon EC2 t3.micro VM (1 GB) booting via EFI:
      
          v6.2-rc2:
          Node 0, zone      DMA
                spanned  4095
                present  3999
                managed  3840
          Node 0, zone    DMA32
                spanned  246652
                present  245868
                managed  178867
      
          v6.2-rc2 + patch:
          Node 0, zone      DMA
                spanned  4095
                present  3999
                managed  3840

                present  245868
