cmpxchg() on some architectures (ia64) doesn't like functions as parameters.
This results in the following compile error on the affected architectures.
fs/aio.c: In function 'aio_thread_fn':
fs/aio.c:1499:1: error: cast specifies function type
Fixes: 6a81013efc40 ("aio: add support for IOCB_CMD_POLL via aio thread helper")

No idea if this is the correct or an acceptable fix.
If not, please consider this to be a bug report.
