3.3-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Russ Anderson <redacted>

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.
