Andrea Bittau afec35e3fe [DCCP] Ackvec: fix soft lockup in ackvec handling code
A soft lockup existed in the handling of ack vector records.
Specifically, when a tail of the list of ack vector records was
removed, it was possible to end up iterating infinitely on an element
of the tail.

Arnaldo Carvalho de Melo 2d0817d11e [DCCP] options: Make dccp_insert_options & friends yell on error
And not the silly LIMIT_NETDEBUG and silently return without inserting
the option requested.

Also drop some old debugging messages associated to option insertion.

Al Viro dd0fc66fb3 [PATCH] gfp flags annotations - part 1
- added typedef unsigned int __nocast gfp_t;

 - replaced __nocast uses for gfp flags with gfp_t - it gives exactly
   the same warnings as far as sparse is concerned, doesn't change
   generated code (from gcc point of view we replaced unsigned int with
   typedef) and documents what's going on far better.

Isolating it, that will be used when we introduce a CCID2 (TCP-Like)
