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") #
