[patch 5/5] iommu/vt-d: Convert allocations to GFP_KERNEL

[Thomas Gleixner <tglx@linutronix.de>]

[-- Attachment #1: iommu-convert-allocations-to-kernel.patch --]

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