4.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Sara Sharon <[email protected]> [ 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.
