struct bpf_cpumask is a BPF-wrapper around the struct cpumask type which
can be instantiated by a BPF program, and then queried as a cpumask in
similar fashion to normal kernel code. The previous patch in this series
makes the type fully RCU safe, so the type can be included in the
rcu_protected_type BTF ID list.
A subsequent patch will remove bpf_cpumask_kptr_get(), as it's no longer
useful now that we can just treat the type as RCU safe by default and do
our own if check.
