Subject: linux-next: build failure after merge of the akpm tree

Hi Andrew,

After merging the akpm tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

fs/aio.c: In function 'aio_rw_vect_retry':
fs/aio.c:1106:6: error: 'opcode' undeclared (first use in this function)

Caused by commit 36bd5dc0c4e2 ("lift sb_start_write/sb_end_write out of
->aio_write()") from the vfs tree interacting with commit 61ead3d450a4
("aio: kill ki_retry") from the akpm tree.

I applied the following fix patch:
