Merge remote-tracking branch 'torvalds/master' into perf/core
To resolve a trivial merge conflict with c302378bc157f6a7 ("libbpf: Hashmap interface update to allow both long and void* keys/values"), where a function present upstream was removed in the perf tools development tree. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
