    Subject[patch] latest 'guaranteed low latency' patch against 2.2.14

    Here is the changelog of

    Changes since lowlatency-2.2.13-A1 (many thanks go to William Montgomery
    who collected most of these bugfixes):

    - fixed trivial bug in #define udelay_resched(n) (William Montgomery)

    - fixed cpu idle race condition which allowed idle task to effectively
    have higher priority than SCHED_FIFO task. (Jamie Lokier and William

    - fixed race in setting need_resched during task switching (me)

    - fixed bottom half processing to always allow bottom half processing
    have priority over user processes. (Andrea Arcangeli and me)

    - fixed signal handling so that a need_resched after a do_signal is
    properly noticed. (me)

    - fixed ret_with_resched race which occurs when an intr sets
    need_resched _after_ it was checked. (Jamie Lokier)

    - ported to 2.2.14 (me)

    Comments, reports welcome.
