lib/kstrtox: common code between kstrto() and simple_strto() functions Currently termination logic (\0 or \n\0) is hardcoded in _kstrtoull(), avoid that for code reuse between kstrto*() and simple_strtoull(). Essentially, make them different only in termination logic. simple_strtoull() (and scanf(), BTW) ignores integer overflow, that's a bug we currently don't have guts to fix, making KSTRTOX_OVERFLOW hack necessary. Almost forgot: patch shrinks code size by about ~80 bytes on x86_64.
