[PATCH v3 0/6] ONE_REG interface for SBI FWFT extension

[Anup Patel]

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

Changes since v1:
 - Dropped have_state in PATCH4 as suggested by Drew
 - Added Drew's Reviewed-by in appropriate patches
