From 7ffcf8ec26f4b94b95b1297131d223b121d951e5 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Wed, 7 Aug 2013 02:01:46 +1000 Subject: powerpc: Fix little endian lppaca, slb_shadow and dtl_entry The lppaca, slb_shadow and dtl_entry hypervisor structures are big endian, so we have to byte swap them in little endian builds. LE KVM hosts will also need to be fixed but for now add an #error to remind us.
