Merge branch 'bpf-share-helpers'

Alexei Starovoitov says:

====================
v1->v2: switched to init_user_ns from current_user_ns as suggested by Andy

Introduce new helpers to access 'struct task_struct'->pid, tgid, uid, gid, comm
fields in tracing and networking.

Share bpf_trace_printk() and bpf_get_smp_processor_id() helpers between
tracing and networking.
====================
