1a567c5cff36ae3a864fa534bf76711398eba4f1 target/riscv/kvm: add 'rva22u64' flag as unavailable
KVM does not have the means to support enabling the rva22u64 profile.
The main reasons are:
- we're missing support for some mandatory rva22u64 extensions in the
KVM module;
- we can't make promises about enabling a profile since it all depends
on host support in the end.
We'll revisit this decision in the future if needed. For now mark the
'rva22u64' profile as unavailable when running a KVM CPU:
$ qemu-system-riscv64 -machine virt,accel=kvm -cpu rv64,rva22u64=true
qemu-system-riscv64: can't apply global rv64-riscv-cpu.rva22u64=true:
'rva22u64' is not available with KVM
