From 27ac3e06d59a2c37cdc5997f65ff82e104ec798a Mon Sep 17 00:00:00 2001 From: David Gibson Date: Tue, 19 Jan 2016 15:57:59 +1100 Subject: [PATCH] spapr: Remove abuse of rtas_ld() in h_client_architecture_support h_client_architecture_support() uses rtas_ld() for general purpose memory access, despite the fact that it's not an RTAS routine at all and rtas_ld makes things more awkward. Clean this up by replacing rtas_ld() calls with appropriate ldXX_phys() calls.
