#     powerpc/ptrace: replace ptrace_report_syscall() with a tracehook call
#     
#     Arch code should use tracehook_*() helpers, as documented in
#     include/linux/tracehook.h, ptrace_report_syscall() is not expected to
#     be used outside that file.
#     
#     The patch does not look very nice, but at least it is correct
#     and opens the way for PTRACE_GET_SYSCALL_INFO API.
