This one specifies where to start MSG_PEEK-ing queue data from. When
set to negative value means that MSG_PEEK works as ususally -- peeks
from the head of the queue always.

When some bytes are peeked from queue and the peeking offset is non
negative it is moved forward so that the next peek will return next
portion of data.

When non-peeking recvmsg occurs and the peeking offset is non negative
is is moved backward so that the next peek will still peek the proper
data (i.e. the one that would have been picked if there were no non
peeking recv in between).

The offset is set using per-proto opteration to let the protocol handle
the locking issues and to check whether the peeking offset feature is
supported by the protocol the socket belongs to.

small note : should be moved down by one line, after SCM_WIFI_STATUS

Other than that, 

You also didn't update all of the arch/*/include/asm/socket.h files.

I took care of all of this, but what should have been a simple matter
of me typing "git am --signoff foo.mbox" and "make" turned into a
10 minute exercise in raking leaves. :-/
