cd28786d6d NetLabel: convert the unlabeled accept flag to use RCU 
Currently the NetLabel unlabeled packet accept flag is an atomic type and it
is checked for every non-NetLabel packet which comes into the system but rarely
ever changed.  This patch changes this flag to a normal integer and protects it
with RCU locking.

1f758d9354 NetLabel: use gfp_t instead of int where it makes sense 
There were a few places in the NetLabel code where the int type was being used
instead of the gfp_t type, this patch corrects this mistake.

32aac18dfa [DCCP] CCID2: Code optimizations 
These are code optimizations which are relevant when dealing with large
windows.  They are not coded the way I would like to, but they do the job for
the short-term.  This patch should be more neat.

Commiter note: Changed the seqno comparisions to use {after,before}48 to handle
               wrapping.

58a5a7b955 [NET]: Conditionally use bh_lock_sock_nested in sk_receive_skb 
Spotted by Ian McDonald, tentatively fixed by Gerrit Renker:

http://www.mail-archive.com/dccp%40vger.kernel.org/msg00599.html

Rewritten not to unroll sk_receive_skb, in the common case, i.e. no lock
debugging, its optimized away.

3c6952624a [DCCP]: Introduce DCCP_{BUG{_ON},CRIT} macros, use enum:8 for the ccid3 states 
This patch tackles the following problem:
       * the ccid3_hc_{t,r}x_sock define ccid3hc{t,r}x_state as `u8', but
         in reality there can only be a few, pre-defined enum names
       * this necessitates addiditional checking for unexpected values
         which would otherwise be caught by the compiler
