From 72176dd0ad36c6d8e13515d085f7a229a55a2985 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Fri, 29 Apr 2016 23:25:37 +1000 Subject: [PATCH] powerpc/mm: Use a helper for finding pte bits mapping I/O area Use a helper instead of open coding with constants. A later patch will drop the WIMG bits and use PowerISA 3.0 defines.
