Instead of generating a struct siginfo before calling arm64_notify_die pass the signal number, tne sicode and the fault address into arm64_notify_die and have it call force_sig_fault instead of force_sig_info to let the generic code generate the struct siginfo. This keeps code passing just the needed information into siginfo generating code, making it easier to see what is happening and harder to get wrong. Further by letting the generic code handle the generation of struct siginfo it reduces the number of sites generating struct siginfo making it possible to review them and verify that all of the fiddly details for a structure passed to userspace are handled properly.
