    Subject[PATCH 5/5] powerpc/ppc32: static ftrace fixes for PPC32
    From: Steven Rostedt <rostedt@gollum.(none)>

    Impact: fix for PowerPC 32 code

    There were some early init code that was not safe for static
    ftrace to boot on my PowerBook. This code must only use relative
    addressing, and static mcount performs a compare of the
    ftrace_trace_function pointer, and gets that with an absolute address.
    In the early init boot up code, this will cause a fault.

    This patch removes tracing from the files containing the offending
    functions.
