John W. Linville says:

====================
This is another flurry of fixes intended for the 3.9 stream...

A mac80211 pull from Johannes:

"Seth fixes a stupid bug I introduced into one of his earlier patches,
Chun-Yeow fixes mesh forwarding and Felix fixes monitor mode. I myself
fixed a small locking issue and, the biggest change here, removed some
nl80211 information with which sometimes the per wiphy information was
getting too large for the typical 4k-minus-overhead. In my -next tree I
have a patch to allow splitting that and add back the information
removed now."

An iwlwifi pull from Johannes:

"I have a fix for a pretty important bug regarding DMA mapping, that
could cause the DMA engine to overwrite data we wanted to send to it, so
that the next time we send it it would be bad. This particularly affects
calibration results. Other than that, three little fixes for the MVM
driver."

But wait, there's more!

Avinash Patil fixes an incorrectly timed delay in mwifiex.

Bing Zhao prevents a crash in SD8688 caused by failing to properly
set a flag before issuing a command.

Felix Fietkau is the big here this time, providing a trio of minor
ath9k fixes and correcting the advertised interface combinations for
rt2x00 when mesh support is disabled.

Finally, Hauke Mehrtens gives us a patch that correctlin initializes
a spin lock in the bcma code.

Please let me know if there are problems!
