This series adds initial support for testing KVM RISC-V 64-bit using kernel selftests framework. The PATCH1 & PATCH2 of this series does some ground work in KVM RISC-V to implement RISC-V support in the KVM selftests whereas remaining patches does required changes in the KVM selftests.
These patches can be found in riscv_kvm_selftests_v3 branch at: https://github.com/avpatel/linux.git
This is actually v3 series so please ignore the "PATCH v4" subject prefix.

Changes since v1:
