mm: nobootmem: fix sign extend problem in __free_pages_memory()
commit 6bc2e853c6b46a6041980d58200ad9b0a73a60ff upstream.
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.
