3.18-stable review patch. If anyone has any objections, please let me know.
------------------ From: Mike Snitzer <[email protected]> commit 013ad043906b2befd4a9bfb06219ed9fedd92716 upstream. sector_div() is only viable for use with sector_t. dm_block_t is typedef'd to uint64_t -- so use div_u64() instead.
