[Patch v2 03/16] iommu/vt-d: Convert allocations to GFP_KERNEL

From: Jiang Liu
Date: Wed Jan 07 2015 - 02:33:20 EST


From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>

No reason anymore to do GFP_ATOMIC allocations which are not harmful
in the normal bootup case, but matter in the physical hotplug
scenario.
