Hi all,

Today's linux-next merge of the tip tree got a conflict in
include/uapi/linux/bpf.h between commit 96be4325f443 ("ebpf: add
sched_cls_type and map it to sk_filter's verifier ops"), 03e69b508b6f
("ebpf: add prandom helper for packet sampling"), c04167ce2ca0 ("ebpf:
add helper for obtaining current processor id"), 94caee8c312d ("ebpf:
add sched_act_type and map it to sk_filter's verifier ops"),
608cd71a9c7c ("tc: bpf: generalize pedit action") and 91bc4822c3d6
("tc: bpf: add checksum helpers") from the net-next tree and commit
2541517c32be ("tracing, perf: Implement BPF programs attached to
kprobes"), d9847d310ab4 ("tracing: Allow BPF programs to call
bpf_ktime_get_ns()") and 9c959c863f82 ("tracing: Allow BPF programs to
call bpf_trace_printk()") from the tip tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
