card with GPS, Bluetooth, WiMax and 802.11 radios. It
runs over SDIO and is typically found on Moorestown
based platform. This driver takes care of the 802.11
part, which is a fullmac one.
If you choose to build it as a module, it'll be called

*
* The purpose of the sk_has_sleeper and sock_poll_wait is to wrap the memory
* barrier call. They were added due to the race found within the tcp code.
*
* Consider following tcp code paths:
*
* CPU1 CPU2
*
* sys_select receive packet
* ... ...
* __add_wait_queue update tp->rcv_nxt
* ... ...

* ... {
* schedule ...
* if (sk->sk_sleep && waitqueue_active(sk->sk_sleep))
* wake_up_interruptible(sk->sk_sleep)
* ...
* }
*
* The race for tcp fires when the __add_wait_queue changes done by CPU1 stay
* in its cache, and so does the tp->rcv_nxt update on CPU2 side. The CPU1
* could then endup calling schedule and sleep forever if there are no more
* data on the socket.
*
* The sk_has_sleeper is always called right after a call to read_lock, so we
* can use smp_mb__after_lock barrier.
