From e4f5d5440bb860a3e8942ca8f7277a7f31798965 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Fri, 27 Apr 2012 09:13:18 -0400 Subject: ftrace/x86: Have x86 ftrace use the ftrace_modify_all_code() To remove duplicate code, have the ftrace arch_ftrace_update_code() use the generic ftrace_modify_all_code(). This requires that the default ftrace_replace_code() becomes a weak function so that an arch may override it.
