3.13.11-ckt24 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Sowmini Varadhan <sowmini.varadhan@xxxxxxxxxx> [ Upstream commit 0edfad5959df7379c9e554fbe8ba264ae232d321 ] Since it is possible for vnet_event_napi to end up doing vnet_control_pkt_engine -> ... -> vnet_send_attr -> vnet_port_alloc_tx_ring -> ldc_alloc_exp_dring -> kzalloc() (i.e., in softirq context), kzalloc() should be called with GFP_ATOMIC from ldc_alloc_exp_dring.
