staging: usbip: Process event flags without delay

The way the event handler works can cause it to delay
events until eventual wakeup for another event.

For example, on device detach (vhci):

 - Write to sysfs detach file
    -> usbip_event_add(VDEV_EVENT_DOWN)
      -> wakeup()

#define VDEV_EVENT_DOWN (USBIP_EH_SHUTDOWN | USBIP_EH_RESET).

 - Event thread wakes up and passes the event to
   event_handler() to process.

 - It processes and clears the USBIP_EH_SHUTDOWN
   flag then returns.

 - The outer event loop (event_handler_loop()) calls
   wait_event_interruptible().

The processing of the second flag which is part of
VDEV_EVENT_DOWN (USBIP_EH_RESET) did not happen yet.
It is delayed until the next event.

This means the ->reset callback may not happen for
a long time (if ever), leaving the usbip port in a
weird state which prevents its reuse.

This patch changes the handler to process all flags
before waiting for another wakeup.

I have verified this change to fix a problem which
prevented reattach of a usbip device. It also helps
for socket errors which missed the RESET as well.

The delayed event processing also affects the stub
side of usbip and the error handling there.

As Manuel Stahl observed, putting data into the naming of an attribute
(beyond what it is for) breaks the one value per attribute rule (in spirit
at least).  Hence we introduce a separate _index attribute for each scan
element to tell userspace the ordering in output from the buffer.

This will generate a lot of sparse warnings as all drivers will have unused
iio_const_attrs created.  The rest of the set will clean these up.

The final patch will remove the old indexing method. It is not here so

staging: ath6kl: Fixing a compile error

The commit fixes a compilation error that was encountered while using
a specific kernel configuration file. The problem was the use of some
functions defined in <linux/semaphore.h> without including the header
file explicitly. It was probably working before because of the
dependency getting implicitly satisfied via some other header file.

Staging: batman-adv: Use refcnt to track usage count of batman_if

get_batman_if_by_netdev and get_active_batman_if may leak data from the
rcu protected list of interfaces. The rcu protected list of all gateway
nodes leaks the actual data outside the read-side critical area. This is
not valid as we may free the data using a call_rcu created callback
after we unlock using rcu_read_unlock. A workaround is to provide a
reference count to be sure that the memory isn't freed to early.

It is currently only to implement the already existing functionality and
doesn't provide the full tracking of all usage cases.

Additionally, we must hardif_hold inside the
rcu_read_lock()..rcu_read_unlock() before we attach to the structure
which "leaks" it. When another function now removed it from its usage
context (primary_if, usage on stack, ...) then we must hardif_put it. If
it is decremented to zero then we can issue the call_rcu to the freeing
function. So "put" is not allowed inside an rcu_read_lock.

Staging: batman-adv: Use synchronize_rcu instead of call_rcu

It is recommended [1] to use synchronize_rcu to simplify the code -
especially when otherwise extra locking is needed to protect other code
from picking stale elements. It also protects us for emitting to many
callbacks which may results in OOM conditions.

The only reason not to use it, would be in performance critical sections
or when we are not allowed to block.
