#     powerpc/livepatch: return -ERRNO values in save_stack_trace_tsk_reliable()
#     
#     To match its x86 counterpart, save_stack_trace_tsk_reliable() should
#     return -EINVAL in cases that it is currently returning 1.  No caller is
#     currently differentiating non-zero error codes, but let's keep the
#     arch-specific implementations consistent.
