pull-request: bpf 2018-01-13

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

The main changes are:

1) Follow-up fix to the recent BPF out-of-bounds speculation
   fix that prevents max_entries overflows and an undefined
   behavior on 32 bit archs on index_mask calculation, from
   Daniel.

2) Reject unsupported BPF_ARSH opcode in 32 bit ALU mode that
   was otherwise throwing an unknown opcode warning in the
   interpreter, from Daniel.

3) Typo fix in one of the user facing verbose() messages that
   was added during the BPF out-of-bounds speculation fix,
   from Colin.
