Subject: [PATCH v2 04/04] iommu/ipmmu-vmsa: Drop LPAE Kconfig dependency
Date: Tue, 15 Mar 2016 04:22:13 +0000 [thread overview]
Message-ID: <20160315042213.22103.15860.sendpatchset@little-apple> (raw)
In-Reply-To: <20160315042136.22103.26570.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>
Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
---
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:
