[PATCH] ppc64: Remove redundant uses of physRpn_to_absRpn
physRpn_to_absRpn is a no-op on non-iSeries platforms, remove the two redundant calls. There's only one caller on iSeries so fold the logic in there so we can get rid of it completely. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
