Expand description

Invalidate hypervisor translation cache for guest physical address

This instruction invalidates any address-translation cache entries that an `HFENCE.GVMA` instruction with the same values of `gaddr` and `vmid` would invalidate.

This fence specifies a single guest physical address; the physical address should be shifted right by 2 bits.
