#     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"
#     
#     * tag 'perf-tools-fixes-2020-07-19' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux:
#       tools arch kvm: Sync kvm headers with the kernel sources
#       perf tools: Sync hashmap.h with libbpf's
