3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Asias He <asias@xxxxxxxxxx>
commit 472b72f2db7831d7dbe22ffdff4adee3bd49b05d upstream.
The page++ is wrong. It makes bio_add_pc_page() pointing to a wrong page
address if the 'while (len > 0 && data_len > 0) { ... }' loop is
executed more than one once.
