powerpc/mm: Update definitions of DSISR bits
This updates the definitions for the various DSISR bits to match both some historical stuff and to match new bits on POWER9. In addition, we define some masks corresponding to the "bad" faults on Book3S, and some masks corresponding to the bits that match between DSISR and SRR1 for a DSI and an ISI. This comes with a small code update to change the definition of DSISR_PGDIRFAULT which becomes DSISR_PRTABLE_FAULT to match architecture 3.0B Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
