From ca0d17277fd101ce4878f92b398b6ab71fb2c287 Mon Sep 17 00:00:00 2001 From: Matt Fleming Date: Sun, 28 Jun 2009 12:53:07 +0100 Subject: [PATCH] sh: Fix the value of MCOUNT_INSN_OFFSET It seems that MCOUNT_INSN_OFFSET was calculating the distance between the wrong functions. The value that should have actually been computed is the distance between ftrace_call and ftrace_stub. I discovered this when I added some code to ftrace_caller.
