pull-request: bpf-next 2018-01-11

The following pull-request contains BPF updates for your *net-next* tree.

The main changes are:

1) Various BPF related improvements and fixes to nfp driver: i) do
   not register XDP RXQ structure to control queues, ii) round up
   program stack size to word size for nfp, iii) restrict MTU changes
   when BPF offload is active, iv) add more fully featured relocation
   support to JIT, v) add support for signed compare instructions to
   the nfp JIT, vi) export and reuse verfier log routine for nfp, and
   many more, from Jakub, Quentin and Nic.

2) Fix a syzkaller reported GPF in BPF's copy_verifier_state() when
   we hit kmalloc failure path, from Alexei.

3) Add two follow-up fixes for the recent XDP RXQ series: i) kvzalloc()
   allocated memory was only kfree()'ed, and ii) fix a memory leak where
   RX queue was not freed in netif_free_rx_queues(), from Jakub.

4) Add a sample for transferring XDP meta data into the skb, here it
   is used for setting skb->mark with the buffer from XDP, from Jesper.
