KVM_GET_REG_LIST will dump all register IDs that are available to KVM_GET/SET_ONE_REG and It's very useful to identify some platform regression issue during VM migration. Patch 1 enabled the KVM_GET_REG_LIST API in riscv and patch 2 added the corresponding kselftest for checking possible register regressions. Both patches were ported from arm64 and tested with Linux 6.4-rc1 on a Qemu riscv virt machine.
