  2. group workqueue fns

    Group together workqueue functions.
    kergon committed with Oct 18, 2011
  3. group endio fns

    Group together endio structs and functions.
    (When looking at the code it's important to know the context code runs in.
    - endio, workqueue, target management, i/o submission etc. - so help people
    understand this by trying to group the 'special' contexts together.)

  7. cputimer: Cure lock inversion

    There's a lock inversion between the cputimer->lock and rq->lock;
    notably the two callchains involved are:
    Where the first one is enabling a CLOCK_PROCESS_CPUTIME_ID timer, and
    the second one is keeping up-to-date.
    This problem was introduced by e8abccb ("posix-cpu-timers: Cure
    SMP accounting oddities").
    Cure the problem by removing the cputimer->lock and rq->lock nesting,
    this leaves concurrent enablers doing duplicate work, but the time
    wasted should be on the same order otherwise wasted spinning on the
    lock and the greater-than assignment filter should ensure we preserve

  3. Avoid using variable-length arrays in kernel/sys.c

    The size is always valid, but variable-length arrays generate worse code
    for no good reason (unless the function happens to be inlined and the
    compiler sees the length for the simple constant it is).
    Also, there seems to be some code generation problem on POWER, where
    Henrik Bakken reports that register r28 can get corrupted under some
    subtle circumstances (interrupt happening at the wrong time?).  That all
    indicates some seriously broken compiler issues, but since variable
    length arrays are bad regardless, there's little point in trying to
    chase it down.
    "Just don't do that, then".

  2. ARM: 7122/1: localtimer: add header linux/errno.h explicitly

    Per the text in  Documentation/SubmitChecklist as below, we should
    explicitly have header linux/errno.h in localtimer.h for ENXIO
    1: If you use a facility then #include the file that defines/declares
       that facility.  Don't depend on other header files pulling in ones
       that you use.
    Otherwise, we may run into some compiling error like the following one,
    if any file includes localtimer.h without CONFIG_LOCAL_TIMERS defined.
