[PATCH v6 18/27] powerpc: define syscall_get_error()

2018-12-13 Thread Dmitry V. Levin
syscall_get_error() is required to be implemented on this architecture in addition to already implemented syscall_get_nr(), syscall_get_arguments(), syscall_get_return_value(), and syscall_get_arch() functions in order to extend the generic ptrace API with PTRACE_GET_SYSCALL_INFO request. Cc: Mich
