This series adds ONE_REG interface for SBI FWFT extension implemented by KVM RISC-V. This was missed out in accepted SBI FWFT patches for KVM RISC-V.
These patches can also be found in the riscv_kvm_fwft_one_reg_v3 branch at: https://github.com/avpatel/linux.git
Changes since v2: - Re-based on latest KVM RISC-V queue - Improved FWFT ONE_REG interface to allow enabling/disabling each FWFT feature from KVM userspace
