use the newer and more pleasant kstrtoul() to replace simple_strtoul(),
because simple_strtoul() is marked for obsoletion.

kstrtoul appears to take its arguments in a different order:

unsigned long long simple_strtoull(const char * cp,
  char ** endp, unsigned int base);

int kstrtoul(const char *s, unsigned int base, unsigned long *res);
