2.6.27.22 worthy ath9k updates

Bug Description

SRU Justification:

Impact: SMP machines can hang when using PCI based atheros devices (not PCI express).

Fix: Two cherry picks from 2.6.27.22 stable

Testcase: Network traffic on SMP based hosts with Atheros pci based devices

---

Hi Guys,

Since we are no longer taking the 2.6.27.y stable updates wholesale for Intrepid, I'm reporting this on behalf of Luis Rodriguez:

"These are worthy for Intrepid. These patches are now part of 2.6.27.22. Without these on SMP machines some PCI 11n atheros devices will hang a box. This is more noticeable on MacBook Pros, but I was finally able to reproduce with a regular card. All PCI express 11n devices from us are OK as PCI express is already serialized. Oh and these are also on 2.6.28.10 and made it into the first release of 2.6.29."

ath9k: implement IO serialization

This is a port of:
commit SHA1 6158425be398936af1fd04451f78ffad01529cb0
for 2.6.27

All 802.11n PCI devices (Cardbus, PCI, mini-PCI) require
serialization of IO when on non-uniprocessor systems. PCI
express devices not not require this.

This should fix our only last standing open ath9k kernel.org

Seems these are also committed in the latest Jaunty head, but not yet available as a package in jaunty-proposed.

Committed to Intrepid kernel version of ath9k.

Also pulled the relevant changes from the upstream wireless repo and committed them to the LBM version of ath9k.

Accepted linux into intrepid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!
