Could you make sure that each individual patch builds cleanly with W=1
C=1? There is a bunch of missing "static" and unused function warnings 
in the first few patches. I presume they are made moot by later patches
but with kernel defaulting to Werror now it's a dangerous game to play,
we don't want to break bisection.

Also I spotted this:

include/net/tcp_authopt.h:59: warning: Function parameter or member 'prefixlen' not described in 'tcp_authopt_key_info'
