The GAIT and all of its entries must be represented by physical addresses as this structure is shared with underlying firmware. We can keep a virtual address of the GAIT origin in order to handle processing in the kernel, but when traversing the entries we must again convert the physical AISB stored in that GAIT entry into a virtual address in order to process it. Note: this currently doesn't fix a real bug, since virtual addresses are indentical to physical ones.
