Nicholas Piggin 343208ffe9 powerpc/64s/syscall: Fix ptrace syscall info with scv syscalls 
commit d72500f992849d31ebae8f821a023660ddd0dcc2 upstream.

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.

Fixes: 7fa95f9ada ("powerpc/64s: system call support for scv/rfscv instructions")
