OK, the new changelog reads: """ debug_vm_pgtable calls has_transparent_hugepage() in multiple places to check if PMD-sized pages are supported, use pgtable_has_pmd_leaves() instead. No functional change intended since the call happens under the CONFIG_TRANSPARENT_HUGEPAGE guard and when CONFIG_TRANSPARENT_HUGEPAGE=y both functions return the same value.
