I think so.

I shall drop these:

mmpage_alloc-bail-out-earlier-on-enomem-in-alloc_contig_migrate_range.patch
mmcompaction-let-isolate_migratepages_rangeblock-return-error-codes.patch
mmcompaction-let-isolate_migratepages_rangeblock-return-error-codes-fix.patch
mm-make-alloc_contig_range-handle-free-hugetlb-pages.patch
mm-make-alloc_contig_range-handle-in-use-hugetlb-pages.patch
mmpage_alloc-drop-unnecessary-checks-from-pfn_range_valid_contig.patch

and these:

mm-cma-change-cma-mutex-to-irq-safe-spinlock.patch
hugetlb-no-need-to-drop-hugetlb_lock-to-call-cma_release.patch
hugetlb-add-per-hstate-mutex-to-synchronize-user-adjustments.patch
hugetlb-create-remove_hugetlb_page-to-separate-functionality.patch
hugetlb-call-update_and_free_page-without-hugetlb_lock.patch
hugetlb-change-free_pool_huge_page-to-remove_pool_huge_page.patch
hugetlb-make-free_huge_page-irq-safe.patch
hugetlb-make-free_huge_page-irq-safe-fix.patch
hugetlb-add-lockdep_assert_held-calls-for-hugetlb_lock.patch

Along with notes-to-self that this:

  https://lkml.kernel.org/r/YGwnPCPaq1xKh/88@hirez.programming.kicks-ass.net

might need attention and that this:

  hugetlb-make-free_huge_page-irq-safe.patch

might need updating.
