Subject: [PATCH v3 bpf-next 0/2] bpf: Add a new API libbpf_num_possible_cpus()
Getting number of possible CPUs is commonly used for per-CPU BPF maps
and perf_event_maps. Add a new API libbpf_num_possible_cpus() that
helps user with per-CPU related operations and remove duplicate
implementations in bpftool and selftests.
