Subject: [PATCH v2 00/11] RISCV: Add KVM_GET_REG_LIST API

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 1-7 re-structured the get-reg-list test in aarch64 to make some
of the code as common test framework that can be shared by riscv.

Patch 8 enabled the KVM_GET_REG_LIST API in riscv and patch 9-11 added
the corresponding kselftest for checking possible register regressions.

The get-reg-list kvm selftest was ported from aarch64 and tested with
Linux 6.4-rc1 on a Qemu riscv virt machine.
