backports: add threaded Coccinelle spatch support

Turns out Coccinelle has threaded support, it lets you
break down the target code you need to parse for a spatch
file into separate buckets, each bucket handling a subset of
the target files needed to be evaluated. This adds support
for that and shaves down the amount of time it gets to
generate target code by 97.19%.

After this patch by using 3 * num_cpus threads:

real    1m33.316s
user    24m6.080s

Using num_cpus threads alone was giving 2m42.012s, its why I
experimented in increasing this. I also experimented with
6 * num_cpus threads as well but the amount of time spent
running didn't reduce, lets keep this at 3 * num_cpus for now
and we can experiment and empirically find the best setting for
any system or just make this configurable.

We had SmPL patch integration first committed via
86d99c9d4 back then we were able to scale to a reasonable
similar time:

For history's purpose here's our run time without Coccinelle on
commit 338c4388cc:

This new changes sets us back on track with the timing for when we first
introduced Coccinelle support we just have a lot 5 Coccinelle patches
now. I hope this shows we should be able to scale with Coccinelle much more
efficiently for collateral evolutions that sprinkle through tons of
files.

Screenshots available using htop before [0] and after the patch [1]
while coccinelle is running, this shows how the system is using
resources much more efficiently when doing spatch evaluation for
patch generation on target code.

    inet: limit length of fragment queue hash table bucket lists

    This patch introduces a constant limit of the fragment queue hash
    table bucket list lengths. Currently the limit 128 is choosen somewhat
    arbitrary and just ensures that we can fill up the fragment cache with
    empty packets up to the default ip_frag_high_thresh limits. It should
    just protect from list iteration eating considerable amounts of cpu.

    If we reach the maximum length in one hash bucket a warning is printed.
    This is implemented on the caller side of inet_frag_find to distinguish
    between the different users of inet_fragment.c.

    I dropped the out of memory warning in the ipv4 fragment lookup path,
    because we already get a warning by the slab allocator.

    Let I2C bus segments behind multiplexers have a class. This allows for
    device auto-detection on these segments. As long as parent segments
    don't share the same class, it should be fine.

    I implemented support in drivers i2c-mux-gpio and i2c-mux-pca954x. I
    left i2c-mux-pca9541 and i2c-mux-pinctrl alone for the moment as I

backports: make BACKPORT_BUILD_LEDS depend on LEDS_CLASS=n

Somehow !LEDS_CLASS and LEDS_CLASS=n seem to be different (likely
because LEDS_CLASS is tristate, but BACKPORT_BUILD_LEDS is just a
bool), so use LEDS_CLASS=n to fix build issues in other cases on
certain kernel configurations.

struct property is missing in the general header files in older kernel
versions. There are different versions of this header depending on the

backports: add netdev_notify_peers()

netif_notify_peers() was renamed to netdev_notify_peers() in kernel
3.7. Replace the calls to netdev_notify_peers() with
netif_notify_peers().

Some older kernel versions do not even have netif_notify_peers(), there
we just remove the call, currently it is only used in the 6lowpan code
and I assume it will still work, but not so good.
