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.
