powerpc/mm: Fixup _HPAGE_CHG_MASK
This was wrongly updated by commit 7aa9a23c69ea ("powerpc, thp: remove infrastructure for handling splitting PMDs") during the last merge window. Fix it up. This could lead to incorrect behaviour in THP and/or mprotect(), at a minimum. Fixes: 7aa9a23c69ea ("powerpc, thp: remove infrastructure for handling splitting PMDs") Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
