Here's the fourth patch series, now under drivers/net/wireless

This code submission has seen a fair amount of testing across SDIO and 
SPI interfaces, using multiple vendors' cw1200 implementations.

It's stabilizing nicely.  Except for the fact that IBSS is still broken, 
I consider this driver ready for submission.  As you can tell from the 
changelog below, there have been a lot of changes since the last 
submission.

Most of the changes revolve around further simplifying IRQ handling and 
eliminating various Kconfig flags.  API updates to v3.8 kernels, major 
roaming state machine fixes, eliminating dynamic block ack configuration 
(due to firmware bugs), and a pile of minor fixes and cleanups round 
this out.

There are still a couple bits of code present for older (<2.6.36 and <3.2) 
kernels, which I will strip out for inclusion in compat-drivers once 
this is mainlined.  (Is there a better process I should follow here?)

As always, comments and feedback welcome.
