    Subject[PATCH 0/2] ftrace: fixes for PPC
    I spent the day chasing a bug that would hang PPC on boot up when ftrace
    is configured in. I found that it was simply a stupid bug I did to
    handle the non MCOUNT_RECORD case. Since I was testing only on x86,
    and the MCOUNT_RECORD is automatically set for dynamic ftrace if
    it is available, I did not test the case where MCOUNT_RECORD was not
    set.

    I have not finished porting MCOUNT_RECORD to PPC, but have found
    that it has caused some issues for archs that do not support it yet.

    This patch series handles these cases.
