Merge branch 'bpf-updates'

Daniel Borkmann says:

====================
BPF updates

Some minor updates to {cls,act}_bpf to retrieve routing realms
and to make skb->priority writable.

Thanks!

v1 -> v2:
 - Dropped preclassify patch for now from the series as the
   rest is pretty much independent of it
 - Rest unchanged, only rebased and already posted Acked-by's kept
====================
