Expand description

Invalidate hypervisor translation cache for all virtual machines and guest physical addresses

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 all guest physical addresses and all virtual machines.
