Linus, please pull from
        git://git.infradead.org/intel-iommu.git

This fixes an oops when attempting to enable 1:1 passthrough mode for
devices on which VT-d translation was disabled anyway. It's actually a
long-standing bug but recent changes (commit 18436afd) have made it
much easier to trigger with 'iommu=pt intel_iommu=igfx_off' on the
command line.
