Subject: Please pull 'fixes-davem' branch of wireless-2.6

Dave,

Here are some fixes for 2.6.24...

The iwlwifi patch is needed because the iwlwifi drivers routinely end-up
associated with the "simple" rate control algorithm, yet those drivers
really only work with their own custom algorithms.  The other rate
control patches are there to satisfy dependencies for this patch.

"mac80211: remove ieee80211_common.h" cleans-up an unused file left
hanging-around after an earlier patch already in 2.6.24.

"mac80211: remove unused driver ops" is really a clean-up, but
"mac80211: use IW_AUTH_PRIVACY_INVOKED rather than IW_AUTH_KEY_MGMT"
depends on it.

"ssb: Fix initcall ordering" changes a subsys_initcall to an
fs_initcall.  This seems like a bit of a hack, but it fixes a real
problem and I'm not sure what cleaner solution is either reasonable
or available.  The comment in the patch explains the reasoning for this
somewhat unique situation.

I think the other patches are plain enough to not require further
comment.  Let me know if there are any problems!

Thanks,

John
