From 45dcd8b8a8ca855591e3ac882d3a7fc255d09d43 Mon Sep 17 00:00:00 2001 From: Pekka Paalanen Date: Tue, 16 Sep 2008 21:56:41 +0300 Subject: [PATCH] ftrace: move mmiotrace functions out of trace.c Moves the mmiotrace specific functions from trace.c to trace_mmiotrace.c. Functions trace_wake_up(), tracing_get_trace_entry(), and tracing_generic_entry_update() are therefore made available outside trace.c.
