Subject: [PATCH v6 01/13 -fix] mm/hugepage pud: Allow arch-specific helper function to check huge page pud support
Date: Wed, 26 Jul 2023 16:22:36 +0530 [thread overview]

Subject: [PATCH] mm/debug_vm_pgtable: Use the new
has_transparent_pud_hugepage()
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.
