The branch condition should be CONFIG_TRANSPARENT_HUGEPAGE instead of
CONFIG_ARCH_HAS_PTE_DEVMAP.

The functions {pmd/pud}_set_huge and {pmd/pud}_clear_huge is not depend on THP.
But now if we want to test these functions, we have to enable THP. So move
{pmd/pud}_huge_tests out of CONFIG_TRANSPARENT_HUGEPAGE.

The call to pfn_pmd() here is redundant.

LGTM, thanks for catching. But does not need a patch of it's
own, instead should be folded with other potential clean ups.

Instead drop the first pfn_pmd(), as that pmd would not be required
when THP is not enabled. Also, please fold this with the first patch.
