Kinda unexpected, but DIV_ROUND_UP() can overflow if passed an argument
bigger than UINT_MAX - DIVISOR. Fix this by testing for "!cpp" before
using it in the following division.

Note that DIV_ROUND_UP() is defined as:
        #define DIV_ROUND_UP(n,d) (((n) + (d) - 1) / (d))

..this will obviously overflow if (n + d - 1) is bigger than UINT_MAX.

Pull trace buffer epoll hang fix from Steven Rostedt:
 "Josef Bacik found a bug in the ring_buffer_poll_wait() where the
  condition variable (waiters_pending) was set before being added to the
  poll queue via poll_wait().  This allowed for a small race window to
  happen where an event could come in, check the condition variable see
  it set to true, clear it, and then wake all the waiters.  But because
  the waiter set the variable before adding itself to the queue, the
  waker could have cleared the variable after it was set and then miss
  waking it up as it wasn't added to the queue yet.

  Discussing this bug, we realized that a memory barrier needed to be
  added too, for the rare case that something polls for a single trace
  event to happen (and just one, no more to come in), and miss the
  wakeup due to memory ordering.  Ideally, a memory barrier needs to be
  added on the writer side too, but as that will kill tracing
  performance and this is for a situation that tracing wasn't even
  designed for (who traces one instance of an event, use a printk
  instead!), this isn't worth adding the barrier.  But we can in the
  future add the barrier for when the buffer goes from empty to the
  first event, as that would cover this case"

This avoids a problem seen with weston (for example) where the display
gets stuck in "black screen" if starting weston first thing after boot.
Possibly mdp5 needs something similar.  The downstream android fbdev
driver always requests DMA_E (or DMA_P) when display is active, rather
than only enabling it on-demand as the drm driver does, which I believe
has the same end result.

87e956e9 changed the fault handler to return -ENOSYS, which causes the
iommu driver to print out a huge splat.  Which wouldn't be quite so bad
if nothing ever faulted.  But seems like some EXA composite operations
generate quite a lot of (seemingly harmless) faults.  That is probably a
userspace problem, but the huge increase in verbosity from iommu fault
dumps makes things kind of unusable.

We probably should actually log *some* message (not conditional on
drm.debug).  But ratelimit it.

Epoll on trace_pipe can sometimes hang in a weird case.  If the ring buffer is
empty when we set waiters_pending but an event shows up exactly at that moment
we can miss being woken up by the ring buffers irq work.  Since
ring_buffer_empty() is inherently racey we will sometimes think that the buffer
is not empty.  So we don't get woken up and we don't think there are any events
even though there were some ready when we added the watch, which makes us hang.
This patch fixes this by making sure that we are actually on the wait list
before we set waiters_pending, and add a memory barrier to make sure
ring_buffer_empty() is going to be correct.

Pull fix for ftrace function tracer/profiler conflict from Steven Rostedt:
 "The rewrite of the ftrace code that makes it possible to allow for
  separate trampolines had a design flaw with the interaction between
  the function and function_graph tracers.

  The main flaw was the simplification of the use of multiple tracers
  having the same filter (like function and function_graph, that use the
  set_ftrace_filter file to filter their code).  The design assumed that
  the two tracers could never run simultaneously as only one tracer can
  be used at a time.  The problem with this assumption was that the
  function profiler could be implemented on top of the function graph
  tracer, and the function profiler could run at the same time as the
  function tracer.  This caused the assumption to be broken and when
  ftrace detected this failed assumpiton it would spit out a nasty
  warning and shut itself down.

  Instead of using a single ftrace_ops that switches between the
  function and function_graph callbacks, the two tracers can again use
  their own ftrace_ops.  But instead of having a complex hierarchy of
  ftrace_ops, the filter fields are placed in its own structure and the
  ftrace_ops can carefully use the same filter.  This change took a bit
  to be able to allow for this and currently only the global_ops can
  share the same filter, but this new design can easily be modified to
  allow for any ftrace_ops to share its filter with another ftrace_ops.

  The first four patches deal with the change of allowing the ftrace_ops
  to share the filter (and this needs to go to 3.16 as well).

  The fifth patch fixes a bug that was also caused by the new changes
  but only for archs other than x86, and only if those archs implement a
  direct call to the function_graph tracer which they do not do yet but
  will in the future.  It does not need to go to stable, but needs to be
  fixed before the other archs update their code to allow direct calls
  to the function_graph trampoline"

Commit "HID: logitech: perform bounds checking on device_id early

ones:
- if the report is not a DJ one, then there is not point in checking

- the receiver (index 0) can also receive some notifications which
  can be safely ignored given the current implementation

Move out the test regarding the report_id and also discards
printing errors when the receiver got notified.
