Hi Joerg,
Here are a couple of urgent fixes for a regression on old Tegra devices
related to IOMMU support. The issue is that many drivers think it's a
good idea to register IOMMU support unconditionally, which is not the
smart thing to do at all on multi-platform kernels. T

The MSM IOMMU driver unconditionally calls bus_set_iommu(), which is a
very stupid thing to do on multi-platform kernels. While marking the
driver BROKEN may seem a little extreme, there is no other way to make
the driver skip initialization. One of the problems is that it do

I agree, it makes more sense to put all this into a single patch.
Applied this way.

When regulator is not selected during kconfig, linking of
the exynos iommu driver fails due to missing symbols.
Fix it!
Frankly, I never observed such issue. Could you provide the .config for
such case? I know that existing
