pull-request: bpf 2019-02-23

Hi David,

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

The main changes are:

1) Fix a bug in BPF's LPM deletion logic to match correct prefix
   length, from Alban.

2) Fix AF_XDP teardown by not destroying umem prematurely as it
   is still needed till all outstanding skbs are freed, from Björn.

3) Fix unkillable BPF_PROG_TEST_RUN under preempt kernel by checking
   signal_pending() outside need_resched() condition which is never
   triggered there, from Stanislav.

4) Fix two nfp JIT bugs, one in code emission for K-based xor, and
   another one to explicitly clear upper bits in alu32, from Jiong.

5) Add bpf list address to maintainers file, from Daniel.
