These trace events will show the caller of hyp_assign_table() as well as information about the region(s) of memory that are affected by the changes in ownership (e.g. source/destination VMIDs and permissions). The trace events also provide information about the time spent in the higher execution layers when the memory is being assigned. Also, expose the mem_prot_info and dest_vm_and_perm_info data structures in the secure_buffer header file, so that they are visible to the trace events header file.
