Merge tag 'perf-tools-fixes-2020-07-19' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into master

Pull perf tooling fixes from Arnaldo Carvalho de Melo:

 - Update hashmap.h from libbpf and kvm.h from x86's kernel UAPI.

 - Set opt->set in libsubcmd's OPT_CALLBACK_SET(). This fixes
   'perf record --switch-output-event event-name' usage"
