So I tested this series and it works fine, with a caveat:

Currently, ath5k exposes tons of 5 GHz channels.  In addition to the other
problems I mentioned in http://marc.info/?l=linux-wireless&m=123825852320853,
it also essentially breaks with regulatory hints from the driver.  This is
because because the Atheros world regdomain allows most channels in the
5 GHz range for passive scanning, whereas the default world regdomain 
disables many of these.  Consequently, scanning takes long enough that 
NM/wpa_supplicant bails.

So, I think the way forward is to include the patch linked above with the
rest of the series.  Although perhaps the last patch moving ath5k/ath9k etc 
under the ath/ directory can be put off a while in case people have patches 
sitting around against the old dir structure.

Anyone who still wants to use all the channels with ath5k can use a custom 
regd or configure the supplicant to scan the specific channels they are 
interested in.
