Christophe Leroy 54357fcafa powerpc/64e: Fix wrong test in __ptep_test_and_clear_young()
[ Upstream commit 5ea0bbaa32 ]

Commit 45201c8794 ("powerpc/nohash: Remove hash related code from
nohash headers.") replaced:

  if ((pte_val(*ptep) & (_PAGE_ACCESSED | _PAGE_HASHPTE)) == 0)
	return 0;

By:

  if (pte_young(*ptep))
	return 0;

But it should be:

  if (!pte_young(*ptep))
	return 0;

Fix it.

Fixes: 45201c8794 ("powerpc/nohash: Remove hash related code from nohash headers.")
