Oh crud!  They also picked the capital K.  All right, standard is
close enough to common sense, who cares.

Below code accepts 'Ki' (standard) and 'ki' (analog to decimal k).  It
also chews the final 'B' if people want to pass it.  Changes are
untested.

And for the curious, the 'u' in ustrtoul stands for "unit".

static int ustrtoul(const char *cp, char **endp, unsigned int base)
{
        unsigned long result = simple_strtoul(cp, endp, base);

        switch (**endp) {
        case 'G':
                result *= 1024;
        case 'M':
                result *= 1024;
        case 'K':
        case 'k':
                result *= 1024;
        /* By dwmw2 editorial decree, "ki", "Mi" or "Gi" are to be used. */
                if ((*endp)[1] == 'i')
                        (*endp) += 2;
                if (**endp == 'B')
                        (*endp) += 1;
        }
        return result;
}
