BPF alignment tests got a conflict because the registers are output as Rn_w instead of just Rn in net-next, and in net a fixup for a testcase prohibits logical operations on pointers before using them. Also, we should attempt to patch BPF call args if JIT always on is enabled. Instead, if we fail to JIT the subprogs we should pass an error back up and fail immediately. Signed-off-by: David S. Miller <davem@davemloft.net>
