From 40f2287bd583f4df4c602c1a29a48df2730fb6d4 Mon Sep 17 00:00:00 2001 From: Jiri Kosina Date: Sun, 11 May 2014 15:15:12 +0300 Subject: IB/mlx4: Implement IB_QP_CREATE_USE_GFP_NOIO Modify the various routines used to allocate memory resources which serve QPs in mlx4 to get an input GFP directive. Have the Ethernet driver to use GFP_KERNEL in it's QP allocations as done prior to this commit, and the IB driver to use GFP_NOIO when the IB verbs IB_QP_CREATE_USE_GFP_NOIO QP creation flag is provided.
