Hi David,

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

We've added 6 non-merge commits during the last 6 day(s) which contain
a total of 8 files changed, 35 insertions(+), 9 deletions(-).

The main changes are:

1) Fix ppc BPF JIT's tail call implementation by performing a second pass
   to gather a stable JIT context before opcode emission, from Eric Dumazet.

2) Fix build of BPF samples sys_perf_event_open() usage to compiled out
   unavailable test_attr__{enabled,open} checks. Also fix potential overflows
   in bpf_map_{area_alloc,charge_init} on 32 bit archs, from Björn Töpel.

3) Fix narrow loads of bpf_sysctl context fields with offset > 0 on big endian
   archs like s390x and also improve the test coverage, from Ilya Leoshkevich.
