[PATCH v2 0/6] Risc-V Kvm Smstateen

[Mayuresh Chitale]

This series adds support to detect the Smstateen extension for both, the
host and the guest vcpu. It also adds senvcfg and sstateen0 to the ONE_REG
interface and the vcpu context save/restore.

Changes in v2:
- Add smstaeen description in riscv/extensions.yaml
- Avoid line wrap at 80 chars
