mm: nobootmem: fix sign extend problem in __free_pages_memory()
Systems with 8 TBytes of memory or greater can hit a problem where only the the first 8 TB of memory shows up. This is due to "int i" being smaller than "unsigned long start_aligned", causing the high bits to be dropped. The fix is to change `i' to unsigned long to match start_aligned and end_aligned. Thanks to Jack Steiner for assistance tracking this down.
