From eed542d6962ba33a689b4007a389f466e407bd74 Mon Sep 17 00:00:00 2001 From: AKASHI Takahiro Date: Tue, 20 May 2014 20:31:04 +0900 Subject: ftrace: Make CALLER_ADDRx macros more generic Most archs with HAVE_ARCH_CALLER_ADDR have pretty much the same definitions of CALLER_ADDRx(n). Instead of duplicating the code for all the archs, define a ftrace_return_address0() and ftrace_return_address(n) that can be overwritten by the archs if they need to do something different. Instead of 7 macros in every arch, we now only have at most 2 (and actually only 1 as ftrace_return_address0() should be the same for all archs). The CALLER_ADDRx(n) will now be defined in linux/ftrace.h and use the ftrace_return_address*(n?) macros. This removes a lot of the duplicate code.
