Ah, I see, in the MAINTAINERS entry

KERNEL VIRTUAL MACHINE FOR RISC-V (KVM/riscv)
M:	Anup Patel <anup.patel@....com>
R:	Atish Patra <atish.patra@....com>
L:	linux-riscv@...ts.infradead.org
T:	git git://github.com/avpatel/linux.git
S:	Maintained
F:	arch/riscv/include/uapi/asm/kvm*
F:	arch/riscv/include/asm/kvm*
F:	arch/riscv/kvm/

the L here should be kvm@...r.kernel.org.  arch/riscv/kvm/ files would
still match RISC-V ARCHITECTURE and therefore
linux-riscv@...ts.infradead.org would be CCed.

Unlike other subsystems, for KVM I ask the submaintainers to include the
patches in their pull requests, which is why you saw no kvm@...r entry
for KVM/s390.  However, it's probably a good idea to add it and do the
same for RISC-V.

Is that what you meant?
