treewide: remove large struct-pass-by-value from tracepoint arguments
- fix trace_hfi1_ctxt_info() to pass large struct by reference instead of by value - convert 'type array[]' tracepoint arguments into 'type *array', since compiler will warn that sizeof('type array[]') == sizeof('type *array') and later should be used instead The CAST_TO_U64 macro in the later patch will enforce that tracepoint arguments can only be integers, pointers, or less than 8 byte structures. Larger structures should be passed by reference. Signed-off-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
