Subject: linux-next: build failure after merge of the iommu tree
Date: Mon, 21 Sep 2020 14:09:01 +1000 [thread overview]
Message-ID: <20200921140901.16adf8c2@canb.auug.org.au> (raw)

Hi all,
After merging the iommu tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:
drivers/gpu/drm/msm/msm_iommu.c: In function 'msm_iommu_pagetable_unmap':
drivers/gpu/drm/msm/msm_iommu.c:46:2: error: implicit declaration of function 'iommu_flush_tlb_all'; did you mean 'iommu_flush_iotlb_all'? [-Werror=implicit-function-declaration]
46 | iommu_flush_tlb_all(to_msm_iommu(pagetable->parent)->domain);
| ^~~~~~~~~~~~~~~~~~~
| iommu_flush_iotlb_all
Caused by commit
aae4c8e27bd7 ("iommu: Rename iommu_tlb_* functions to iommu_iotlb_*")
interacting with commit
b145c6e65eb0 ("drm/msm: Add support to create a local pagetable")
from the drm-msm tree.
I have applied the following merge fix patch. Someone will need to tell
Linus about this fix up when the trees get merged.
