Merge branch 'lighten uapi/bpf.h rebuilds'

Jakub Kicinski says: ==================== Last change in the bpf headers - disentangling BPF uapi from netdevice.h. Both linux/bpf.h and uapi/bpf.h changes should now rebuild ~1k objects down from the original ~18k. There's probably more that can be done but it's diminishing returns. Split into two patches for ease of review. ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org>
