Merge remote-tracking branch 'torvalds/master' into perf-tools-next
Sync with upstream to pick up the perf-tools patches that updates the
header files copies to address the check_header.sh warnings. There are
also some libbpf updates, better pick those to be on the same page with
libbpf since perf uses it in various places.
