From f201987b843910ae929c5ed66700d910b29e9c15 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Tue, 19 Jan 2016 15:57:54 +1100 Subject: [PATCH] spapr: Remove rtas_st_buffer_direct() rtas_st_buffer_direct() is a not particularly useful wrapper around cpu_physical_memory_write(). All the callers are in rtas_ibm_configure_connector, where it's better handled by local helper.
