2.6.33-stable review patch. If anyone has any objections, please let us know.

------------------
From: FUJITA Tomonori <fujita.tomonori(a)lab.ntt.co.jp>

commit f33d7e2d2d113a63772bbc993cdec3b5327f0ef1 upstream.

dma_sync_single_range_for_cpu() and dma_sync_single_range_for_device() use
a wrong address with a partial synchronization.
