[PATCH v2 04/04] iommu/ipmmu-vmsa: Drop LPAE Kconfig dependency

2016-03-14 Thread Magnus Damm 
From: Magnus Damm 

Neither the ARM page table code enabled by IOMMU_IO_PGTABLE_LPAE
nor the IPMMU_VMSA driver actually depends on ARM_LPAE, so get
rid of the dependency.

Tested with ipmmu-vmsa on r8a7794 ALT and a kernel config using:
 # CONFIG_ARM_LPAE is not set

Signed-off-by: Magnus Damm 
Acked-by: Laurent Pinchart

 Changes since V1:
 - Rebased on top of ARCH_RENESAS change
 - Added Acked-by from Laurent

 This time the result also compiles on x86. Need to be
 applied as last patch in the following series:
