[ Upstream commit 6437a549ae178a3f5a5c03e983f291ebcdc2bbc7 ]
On ARMv5 and earlier, a randconfig build can still run into
WARNING: unmet direct dependencies detected for IOMMU_IO_PGTABLE_LPAE
Depends on [n]: IOMMU_SUPPORT [=y] && (ARM [=y] || ARM64 || COMPILE_TEST [=y]) && !GENERIC_ATOMIC64 [=y]
Selected by [y]:
- DRM_PANFROST [=y] && HAS_IOMEM [=y] && DRM [=y] && (ARM [=y] || ARM64 || COMPILE_TEST [=y] && !GENERIC_ATOMIC64 [=y]) && MMU [=y]
Rework the dependencies to always require a working cmpxchg64.
Fixes: db594ba3fc ("drm/panfrost: depend on !GENERIC_ATOMIC64 when using COMPILE_TEST")
