====================
pull-request: bpf 2020-08-15

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

We've added 23 non-merge commits during the last 4 day(s) which contain
a total of 32 files changed, 421 insertions(+), 141 deletions(-).

The main changes are:

1) Fix sock_ops ctx access splat due to register override, from John Fastabend.

2) Batch of various fixes to libbpf, bpftool, and selftests when testing build
   in 32-bit mode, from Andrii Nakryiko.

3) Fix vmlinux.h generation on ARM by mapping GCC built-in types (__Poly*_t)
   to equivalent ones clang can work with, from Jean-Philippe Brucker.

4) Fix build_id lookup in bpf_get_stackid() helper by walking all NOTE ELF
   sections instead of just first, from Jiri Olsa.

5) Avoid use of __builtin_offsetof() in libbpf for CO-RE, from Yonghong Song.

6) Fix segfault in test_mmap due to inconsistent length params, from Jianlin Lv.

7) Don't override errno in libbpf when logging errors, from Toke Høiland-Jørgensen.

8) Fix v4_to_v6 sockaddr conversion in sk_lookup test, from Stanislav Fomichev.

9) Add link to bpf-helpers(7) man page to BPF doc, from Joe Stringer.
