Except for the RISC-V part, this can be a pure revert of commit b99040853738 ("KVM:
Pass kvm_init()'s opaque param to additional arch funcs").  I think it makes sense
to process it as a revert, with a short blurb in the changelog to note that RISC-V
is manually modified as RISC-V support came along in the interim.
