powerpc/64e: Fix wrong test in __ptep_test_and_clear_young()
Commit 45201c879469 ("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: 45201c879469 ("powerpc/nohash: Remove hash related code from nohash headers.")
