[PATCH 1/4] Various VT-d code cleanup
This patch maps RMRR in intel_iommu_add_device() if the device has RMRR;
move domain_context_mapping() to be in front of list_move() in
reassign_device_ownership().
Currently, hypervisor sets up devices and RMRR for dom0, and dom0 also
adds devices for itself via hypercall. This is obviously duplicate. In
order to allow old dom0 kernels to work with iommu-capable platforms,
maybe it cannot be removed now. But what time is suitable to solve it?
