-The H (hypervisor) extension specifies that when a guest-page fault is caused by
-an implicit memory access of VS-stage address translation, the reported
-exception is either a load or store/AMO guest-page fault based not on the
-original instruction type but rather on whether the memory access attempted for
-VS-stage translation was a read or a write of memory. VS-stage address
-translation can thus cause a shadow stack instruction to raise a load
