Re: [PATCH 01/12] Security: Add CAP_COMPROMISE_KERNEL

Mm. The question is whether we can reliably determine the ranges a device 
should be able to access without having to trust userspace (and, ideally, 
without having to worry about whether iommu vendors have done their job). It's 
pretty important for PCI passthrough, so we do need to care.
