Dear David, Eric,

this patch-set is mostly intended to fix sparse and LOCKDEP warnings.
It mostly contains some my previous patches reworked and extended according
to the hints from Eric Dumazet and Fengguang Wu. Many thanks to they!

Changes since v1:
1. A new patch from Tony Cheneau was added. The fragmentation stops working
after some amount of packets sent. This patch fixes this issue.
2. 6lowpan fragment deleting routine: I removed spinlocks from timer_expired
handler and use spin_lock_bh to disable concurrency races with timer interrupt.
3. at86rf230 irq handler was a little bit modified

Series applied, but you don't need to grab a spinlock to only
load one interger from some datastructure.  I mean:

	lock();
	ret = p->foo;
	unlock();

is completely pointless.
