powerpc/mm: Make pte_pgprot return all pte bits
Other archs do the same and instead of adding required pte bits (which got masked out) in __ioremap_at(), make sure we filter only pfn bits out. Fixes: 26973fa5ac0e ("powerpc/mm: use pte helpers in generic code") Reviewed-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
