Linus Torvalds ae453eef92 BPF fixes: 
- Fix tcp_bpf_sendmsg() error path mistaking a concurrently-freed
   sk_psock->cork for the local temporary message and freeing it
   again. (Chengfeng Ye)
 
 - Reject passing scalar NULL to nonnull arg of a global subprog.
   Previously the verifier did not account for the cases directly
   passing scalars to a global subprog, e.g.: 'global_func(0);'
   would pass even if 'global_func' argument was marked nonnull.
   (Amery Hung)
