Rafał Miłecki 3f7bb3f34c b43: AC-PHY: prepare place for developing new PHY support
There are new (not anymore?) Broadcom 802.11ac wireless cards based on
chipsets like BCM4352 and BCM4360. They use a new PHY type (called
simply AC) that will require new specific code.

Michael Büsch a75d46a4f4 b43: Fix locking FIXME in beacon update top half
b43 has a FIXME about locking in the mac80211 set-beacon-int callback for a long time.
As it turns out there actually is a tiny race window that could result in
a use-after-free bug of the 'current_beacon' memory.
Nobody ever reported this, so it probably never happened.

Fix this by adding a spin lock that protects the current_beacon access.
We must not be in atomic context while accessing hardware (due to SDIO),
so the beacon update bottom half has to clone the skb and release the lock
before writing it to hardware.

Let's all hope that this stops the troll who is trying to submit incorrect
fixes for this issue repeatedly.
And let's hope that I'm not a troll, too, who just hides even more evil code
in an even more complex attempt to fix the issue.
