Merge tag 'slab-for-5.17-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab

Pull more slab updates from Vlastimil Babka:
 "Finish the conversion to struct slab by removing slab-specific fields
  from struct page.

  The first slab update (see merge commit ca1a46d6f506) did most of the
  conversion, but there was also series in iommu tree removing the
  iommu's usage of struct page 'freelist' field, blocking the final
  struct page cleanup.

  Now that the iommu changes have been merged, we can finish the job"
