Subject: [PATCH v7 07/07] iommu/ipmmu-vmsa: Drop LPAE Kconfig dependency
Date: Tue, 07 Mar 2017 12:17:53 +0900 [thread overview]
Message-ID: <148885667392.28553.14961612755669401435.sendpatchset@little-apple> (raw)
In-Reply-To: <148885660307.28553.995847796823338863.sendpatchset@little-apple>
From: Magnus Damm <damm+renesas@opensource.se>
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 <damm+renesas@opensource.se>
