pull-request: bpf 2018-01-18

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

The main changes are:

1) Fix a divide by zero due to wrong if (src_reg == 0) check in
   64-bit mode. Properly handle this in interpreter and mask it
   also generically in verifier to guard against similar checks
   in JITs, from Eric and Alexei.

2) Fix a bug in arm64 JIT when tail calls are involved and progs
   have different stack sizes, from Daniel.

3) Reject stores into BPF context that are not expected BPF_STX |
   BPF_MEM variant, from Daniel.

4) Mark dst reg as unknown on {s,u}bounds adjustments when the
   src reg has derived bounds from dead branches, from Daniel.
