mm-hugepage-pud-allow-arch-specific-helper-function-to-check-huge-page-pud-support-fix.patch
This patch was dropped because it was folded into mm-hugepage-pud-allow-arch-specific-helper-function-to-check-huge-page-pud-support.patch

Subject: mm/debug_vm_pgtable: Use the new has_transparent_pud_hugepage()
Date: Wed, 26 Jul 2023 13:45:28 +0530
Use the new helper to check pud hugepage support. Architecture like ppc64
will enable the config value CONFIG_HAVE_ARCH_TRANSPARENT_HUGEPAGE_PUD and
can still have pud hugepage support disabled for hash translation.
