#     powerpc/syscalls: Fix syscall tracing
#     
#     Recently in commit fbf508da7440 ("powerpc: split compat syscall table
#     out from native table") we change the layout of the system call table.
#     Instead of having two entries for each syscall number, one for the
#     regular entry point and one for the compat entry point, we now have
#     separate tables for regular and compat.
#     
#     This inadvertently broke syscall tracing (CONFIG_FTRACE_SYSCALLS),
#     because our implementation of arch_syscall_addr() knew about the
#     layout of the table (it did nr * 2).
#     
#     We can fix it just by dropping our version of arch_syscall_addr() and
#     using the generic version which does:
#     
#             return (unsigned long)sys_call_table[nr];
#     
#     Fixes: fbf508da7440 ("powerpc: split compat syscall table out from native table")
