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.

Changed since v1:
* rebase to Andrew's changes
* fix coding style

Andrew Jones (7):
KVM: arm64: selftests: Replace str_with_index with strdup_printf
KVM: arm64: selftests: Drop SVE cap check in print_reg
KVM: arm64: selftests: Remove print_reg's dependency on vcpu_config
KVM: arm64: selftests: Rename vcpu_config and add to kvm_util.h
KVM: arm64: selftests: Delete core_reg_fixup
KVM: arm64: selftests: Split get-reg-list test code
KVM: arm64: selftests: Finish generalizing get-reg-list

Haibo Xu (4):
KVM: riscv: Add KVM_GET_REG_LIST API support
KVM: riscv: selftests: Make check_supported arch specific
KVM: riscv: selftests: Skip some registers set operation
KVM: riscv: selftests: Add get-reg-list test
