From: Lu Baolu <baolu.lu@xxxxxxxxxxxxxxx> The updates of the PTEs in the nested page table will be propagated to the hardware caches on both IOMMU (IOTLB) and devices (DevTLB/ATC). Add a new domain op cache_invalidate_user for the userspace to flush the hardware caches for a nested domain through iommufd. No wrapper for it, as it's only supposed to be used by iommufd. Then, pass in invalidation requests in form of a user data array conatining a number of invalidation
