Subject[PATCH 4.9 118/329] mac80211: fix calling sleeping function in atomic context
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sara Sharon <sara.sharon@intel.com>

[ Upstream commit 95f3ce6a77893ac828ba841df44421620de4314b ]

sta_info_alloc can be called from atomic paths (such as RX path)
so we need to call pcpu_alloc with the correct gfp.

Fixes: c9c5962b56c1 ("mac80211: enable collecting station statistics per-CPU")
