+** vmm_set_XA
+**
+** This function sets the eXtended Architecture flags for the specifed VM.
+** 
+** We need to return the result in the return code rather than in the return parameters
+** because we need an architecture independent format so the results are actually 
+** usable by the host. For example, the return parameters for 64-bit are 8 bytes wide vs.
+** 4 for 32-bit. 
+** 
+** Note that this function does a lot of the same stuff as vmm_tear_down_context
+** and vmm_init_context.
+**
+** Inputs:
+**             act - pointer to current thread activation structure
+**             index - index returned by vmm_init_context
+**             flags - the extended architecture flags
+**             
+**
+** Outputs:
+**             KERN_SUCCESS if vm is valid and initialized. KERN_FAILURE if not.
+**             Also, the internal flags are set and, additionally, the VM is completely reset.
