This patch is causing some problems in the iwlwifi driver. Often when
one of these RCU locks are held the driver tries to send a command to
the device and waits for the response, or it does some other activity
requiring sleeping. This causes numerous BUG messages as seen below:

BUG: sleeping function called from invalid context at
/home/rchatre/wifi/repos.git/iwlwifi-2.6/kernel/mutex.c:209

 [<dc9d186a>] ieee80211_sta_wmm_params+0x165/0x195 [mac80211]

Ouch, sorry. Try this patch please.

This patch made those BUG messages disappear. Thank you very much.
