Nicholas Piggin d72500f992 powerpc/64s/syscall: Fix ptrace syscall info with scv syscalls ... The scv implementation missed updating syscall return value and error value get/set functions to deal with the changed register ABI. This broke ptrace PTRACE_GET_SYSCALL_INFO as well as some kernel auditing and tracing functions. Fix. tools/testing/selftests/ptrace/get_syscall_info now passes when scv is used.
