Scott's right. rh_attach_region() never supported anything above "(unsigned long)
-MAXERR". Perhaps I should add a check for that?
/* Round start up */
s = (s + m) & ~m;
+ if (IS_ERR_VALUE(s))
+ return -EINVAL;
/* Round end down */
e = e & ~m;
The same patch should be applied to rh_detach_region() and rh_alloc_fixed().
