3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christoph Hellwig <hch@lst.de>
commit 8a9d6e964d318533ba3d2901ce153ba317c99a89 upstream.
The blocklayout code does not compile cleanly for a 32-bit sector_t, and also has no reliable checks for devices sizes, which makes it unsafe to use with a kernel that doesn't support large block devices.
