[PATCH v3 linux-next] iommu: Enable LPAE pagetable on ARM and ARM64 only

From: Vincent StehlÃ
Date: Mon Feb 23 2015 - 19:20:45 EST

LPAE iommu page table makes sense only for ARM and ARM64 architectures. Add the
corresponding dependency in Kconfig (and enable for COMPILE_TEST, too, as per
Laurent's suggestion).

Best regards,
