Hi David, hi Jakub,

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

We've added 6 non-merge commits during the last 10 day(s) which contain
a total of 7 files changed, 11 insertions(+), 236 deletions(-).

The main changes are:

1) Fix BPF ringbuf to allocate its area with VM_MAP instead of VM_ALLOC
   flag which otherwise trips over KASAN, from Hou Tao.

2) Fix unresolved symbol warning in resolve_btfids due to LSM callback
   rename, from Alexei Starovoitov.

3) Fix a possible race in inc_misses_counter() when IRQ would trigger
   during counter update, from He Fengqing.

4) Fix tooling infra for cross-building with clang upon probing whether
   gcc provides the standard libraries, from Jean-Philippe Brucker.

5) Fix silent mode build for resolve_btfids, from Nathan Chancellor.

6) Drop unneeded and outdated lirc.h header copy from tooling infra as
   BPF does not require it anymore, from Sean Young.

Please consider pulling these changes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf.git

Thanks a lot!
