[PATCHv2 perf/core 0/2] libbpf: Synchronize implementations

From: Joe Stringer
Date: Wed Nov 16 2016 - 12:43:48 EST

Update tools/lib/bpf to provide more functionality and improve interoperation
with other tools that generate and use eBPF code:
* The kernel uapi headers are a bit newer than the version in the tools/
directory; synchronize those.
* samples/bpf/libbpf* has a bit more functionality than tools/lib/bpf, so
extend tools/lib/bpf/bpf* with these functions to bring them into parity.

I've got a separate series to update samples/bpf/* to rely on these libraries,
but there's a conflict with davem's tree at the moment so I suppose that the
way forward is to get these patches through first, then take the samples
through net-next at a later time.

v2: Don't shift non-bpf code into libbpf.
Drop the patch to synchronize ELF definitions with tc.
