3.2.47-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: "Steven Rostedt (Red Hat)" <rostedt@xxxxxxxxxxx>
commit 7f49ef69db6bbf756c0abca7e9b65b32e999eec8 upstream.
As ftrace_filter_lseek is now used with ftrace_pid_fops, it needs to
be moved out of the #ifdef CONFIG_DYNAMIC_FTRACE section as the
ftrace_pid_fops is defined when DYNAMIC_FTRACE is not.
Cc: Namhyung Kim <namhyung@xxxxxxxxxx>

[bwh: Backported to 3.2:
- ftrace_filter_lseek() is static and not declared in ftrace.h
- 'whence' parameter was called 'origin']
