Hi Andrew,

After merging the akpm-current tree, today's linux-next build
(x86 allmodconfig) failed like this:

  CC [M]  drivers/net/ethernet/netronome/nfp/nfp_app.o
In file included from /home/broonie/tmpfs/next/drivers/net/ethernet/netronome/nfp/nfp_asm.c:40:0:

  WARN_ON(id > 3 || (off && mode != NN_LM_MOD_NONE));
  ^
cc1: some warnings being treated as errors

Caused by some reliance on an implicit include being exposed by a header
reorganization in your tree.  I'll add a patch for this which I'll post,
probably tomorrow morning.
