[Xen-devel] [PATCH 07/28] ARM: GICv3 ITS: introduce device mapping

The ITS uses device IDs to map LPIs to a device. Dom0 will later use those IDs, which we directly pass on to the host. For this we have to map each device that Dom0 may request to a host ITS device with the same identifier. Allocate the respective memory and enter each device into an rbtree to
