    Subject[PATCH v7 00/17] ftrace for MIPS
    Date
    From: Wu Zhangjin <wuzhangjin@gmail.com>

    This patchset incorporates the feedbacks from Steven, Frederic, David, Richard
    and Michal.

    The main changes from the v6 version:

    o tracing: add IRQENTRY_EXIT section for MIPS: keep the return value of
    do_IRQ_* be void as the original version does.

    o tracing: define a new __time_notrace annotation flag: replace the old
    __arch_notrace by __time_notrace, just keep the stuff simpler.

    o tracing: make ftrace for MIPS work without -fno-omit-frame-pointer: prepare
    for the future -fomit-frame-pointer, Seems we are not necessary to enable
    -fno-omit-frame-pointer with -pg

    o tracing: make ftrace for MIPS more robust: add the safe load/store
    operations for MIPS

    o tracing: add function graph tracer support for MIPS: make the searching of
    the location of return address(ra) clearer.

    o tracing: reserve $12(t0) for mcount-ra-address of gcc 4.5
    tracing: make function graph tracer work with -mmcount-ra-address

    All of these updates have been pused into:

    git://dev.lemote.com/rt4ls.git linux-mips/dev/ftrace-upstream

    All of these stuff and their combinations have been tested with gcc 4.4 & 4.5
    on a YeeLoong netbook.

    Welcome to play with it and give more feedbacks ;)

    Thanks & Regards,
    Wu Zhangjin
