This is supported on `target_arch="riscv64"` only.
Expand description

Invalidate hypervisor translation cache for guest physical address and virtual machine

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, shifted right by 2 bits, and a single virtual machine by virtual machine identifier (VMID).
