In addition to above mentioned lists, we insist of having a separate
KVM RISC-V list which can be CCed for non-kernel patches for projects
such as QEMU, KVMTOOL, and Libvirt. This KVM RISC-V list can also
be used for general queries related to KVM RISCV.

For KVM RISC-V, we will always CC both kvm@vger.kernel.org and
linux-riscv@lists.infradead.org.
