This happens frequently in the > ptrace code because the addr and data arguments to sys_ptrace, > ptrace_request, arch_ptrace et al. are long rather than unsigned long. > > There doesn't seem to be any good reason not to have them be unsigned, > so this changes them from long to unsigned long. > > Signed-off-by: Paul Mackerras <paulus@xxxxxxxxx> Thanks for fixing this: Acked-by: David S. Miller <davem@xxxxxxxxxxxxx> I thought there might be some cases that cared about negative values of 'addr', but I can't see any. -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
